Easy way to solve Question No 6: 3 men do 1/2 amount of work so 1 men does 1/6 amt of work 4 boys do 1/6 amt of work so 1 boy does 1/24 amt of work Therefore, 8 Men and 8 Boys do the work in, 8x(1/6)+8x(1/24) = 5/3 Inverting would give 3/5 P.S : I Really like these tutorials.. Now I have more confidence in solving Aptitude questions!
10 th sum p= 16 ( 3) Q= 12( 4) So total 48 units of work and per 2 day they r doing 7 parts 2-7 parts ?-48 parts 96/7 = so per 13 days they do 91 parts and they left 5 parts na so 13 th day p do the work so per day p do 4 parts na so 1 part remained so this one part done by q in 1/3 days so total 14(1/3) but it is not working because 14× 7 = 98 it is more than total units so it is wrong were I did wrong plz explain na
Q9:: A already is working 8 hours/day . Now we can calculate the no. of days for B to finish if he works for 8hours/day. B's total hours=8*10=80 if B is working 8hours/day=80/8=10 Now calculate simply A and B working together = 1/12 + 1/10 ans =60/11
simple and clean way for ques no. 7- let n be the days they worked together we know total amount of work done is 1 so, ( 1/20+1/25 )*n + 10*( 1/25 ) = 1 9n/100 + 2/5 = 1 9n + 40 = 100 n = 60/9 = 20/3
An easier method of solving question 10 just use the normal technique that he described earlier and at the end divide by 2 because only one person works on a given day Raj does 1/16 work in 1 day Suraj does 1/12 work in 1 day Raj + Suraj when working alternating, = 1/12 + 1/16 work in 2 days = 1/2*( 1/12 + 1/16) work in 1 day = 7/96 work in 1 day Raj + Suraj does 7/96 work in 1 day, so, they do the work in 96/7 = 13.75 days
For Qn 2 We can use an eqn M1 ×D1×H1/W1 = M2×D2×H2/W2 Where M1, M2 - no of men D1, D2 - no of days H1, H2 - no of hours W1 ,W2 - no of work This eqn can be used in such type of problems. In this question M1 = 24 M2= 30 D1 = 10 D2 =? Therefore , M1×D1 = M2 ×D2 D2 =M1 ×D1/M2 = 24×10/30 = 8 days 😇😇😇😇
Question 7 Lcm of 20 and 25 is 100. Efficiency of sita and Gita 5 & 4. Gita for 10 days= 4*10. Remaining 60 both has done. 60÷9 = 20/3.... u can do like previous model too.
@@ramyapeko219 Raj work -> 16 days -> 1/16 work/day Suraj work -> 12 days -> 1/12 work/day They work on alternate days So for 2 days work done = Raj's 1 day work + Suraj's 1 day work = 1/16 + 1/12 2 days work = 7/48 Total work to be done is 1. Therefore for 2 days -> 7/48 so for ? days -> 1 i.e. completing the work by simply cross multiplying ? days = (2 x 1)/(7/48) ? days = 13.7 days

9th question can be done in a simpler way. I got the same ans doing less calculation. A's one day work = 1/12 [8hrs per day] B's one day work = 1/8 [10hrs per day] if 1/8 work is done in 10 hrs, the amount of work done in 8 hours will be 1/10 now we have both A and B 8 hrs work per day 1/12 + 1/10 = 11/60(one day's work together) total time taken = 60/11 days

Sir A short talk I will tell There are many short tricks and method which can solve problems in 2-3 lines only. You make it more complicated and even tough for beginners students. So take in mind short tricks bcoz in govt time given is very low. But your effort is great towards your students
in the question q is more efficient than p ..so i took 100% for p for easy calculation...so p:q is 100:125 means 4:5 work and time efficiency for p:q is 1/4x:1/5x....means 5x:4x..x is time here...5 and 4 are work part.. already we know p has done in 30 days...5x is 30 means 5x=30 so x =6...now we have to find the days took by q...so q part is 4x so 4*6=24
For 36:12 Mt thought process is.. Let Raj takes x days and Suraj takes y days while working at alternative days. X/16 + Y/12 = 1 Simplifying... 3X + 4Y = 48 Now, values of X and y must be the closest.. Half the left most value i.e. 48/2=24 as both are working alternate days... Values of X may be 6, 7, 8 and corresponding values of y becomes 7.5, 6+3/4, 6. Closest pair is 7 and 6+3/4.... Total days = 13+ 3/4
Q)9) 1day work(A)=1/12 1 hr work of 8hrs=1/12*8 1day work(B)=1/8 1 hr work of 10hrs=1/8*10 Total 8hrs working of A and B in oneday=8/12*8 + 8/8*10 =11/60,. Invert. So ans=60/11
For the 8th Question: Let P+Q finish work in N days P+Qs 1day work = 1/N ...eq1 When P works alone,he takes:N+25 days Hence Ps 1day work = 1/N+25 When Q works alone,he takes: N+9 days Hence Qs 1day work = 1/N+9 Using eqn1: 1/N+25 + 1/N+9 = 1/N Solving N=15 (Ans.)
One of the best videos I have watched so far, covered almost all the types of question and that too with proper concepts... Keep it up, more power to you!!!!
sir, the 9th question can be done in a much more simpler manner just by finding the one day work by A AND B in 8 and 10 hrs respectively ie for A 1/12 amt of work in 8hrs for B 1/8 amt of work in 10hrs which can be found for 8hrs so B's 8hr work will be 1/10 (using unitary method) so now.....both have same 8hrs work so (1/12)+(1/10)=11/60..................................total work in one day by both so the answer would be by inverting ie......60/11....(saves lots of calculation time) thankyou,,,
Unitary method is nothing but cross multiply. In this case: B can do 1/8 amount of work in 10 hours then B can do x amount of work in 8 hours. After cross multiplying, we get 10x = 8/8 i.e. x = 1/10

SOLUTION OF THIS PROBLEM PLEASE: A and B together can complete 75% of a work in 33 days while A, B and C together can complete the whole work in 26 days. If ‘C’ is 12.5% more efficient than B then find the time taken by A and C together to complete 70% of the work.
Really good question I have solved it more than half and I know which steps I should take next but I am lazy rn to do this much calculation For proof (total days required to work be done by A and B is 44 days, work done by c in one day is 9/572, work done by B in one day is 9/1.125*572 ....)

An easier method of solving question 10
just use the normal technique that he described earlier and at the end divide by 2 because only one person works on a given day
Raj does 1/16 work in 1 day
Suraj does 1/12 work in 1 day
Raj + Suraj when working alternating,

= 1/2*( 1/12 + 1/16) work in 1 day

For Qn 2
We can use an eqn
M1 ×D1×H1/W1 = M2×D2×H2/W2
Where M1, M2 - no of men
D1, D2 - no of days
H1, H2 - no of hours
W1 ,W2 - no of work
This eqn can be used in such type of problems. In this question
M1 = 24
M2= 30
D1 = 10
D2 =?
Therefore ,
M1×D1 = M2 ×D2
D2 =M1 ×D1/M2

For 36:12 Mt thought process is..
Let Raj takes x days and Suraj takes y days while working at alternative days.
X/16 + Y/12 = 1
Simplifying...
3X + 4Y = 48
Now, values of X and y must be the closest..
Half the left most value i.e. 48/2=24 as both are working alternate days...
Values of X may be 6, 7, 8 and corresponding values of y becomes 7.5, 6+3/4, 6. Closest pair is 7 and 6+3/4....
Total days = 13+ 3/4
How the corresponding values in to 7.5, 6+3/4 and 6
If we put 6 in place of X (in equation) the Y value will be equal to 7.5, similarly, other values...
question number 2 simplified
24 man= 10 days

Thanks, Ravi!
Completely cleared all the doubts thank u so much sir for ur clear explanation.
sir, the 9th question can be done in a much more simpler manner
just by finding the one day work by A AND B in 8 and 10 hrs respectively
ie
for A
1/12 amt of work in 8hrs
for B
1/8 amt of work in 10hrs which can be found for 8hrs
so B's 8hr work will be 1/10 (using unitary method)
so now.....both have same 8hrs work
so (1/12)+(1/10)=11/60..................................total work in one day by both
so the answer would be by inverting ie......60/11....(saves lots of calculation time)
thankyou,,,
What is unitary method
Anubhav Verma Q6 can also be done by unitary method
What is unitary method can u explain it
Unitary method is nothing but cross multiply.
In this case:
B can do 1/8 amount of work in 10 hours then B can do x amount of work in 8 hours. After cross multiplying, we get
10x = 8/8 i.e. x = 1/10
Bro compare to your solution their method is more easier
Simple way:A:B=5:1
Difference 5-1=4
So,A= 5/4×60=75 days
B=1/4×60=15 days.
Wrong (A is faster than B then how would it takes 75 days)
It should be A:B: :1:5

The short trick used in the question no. 8 can be used for any number of workers or just for 2 workers?
Sir plz solve this: A completed a piece of work in 60 days and B is 50% more efficient than A. They start working together but B left the work after 5 days then A can complete the work in?

That was an extraordinary video! I understood time and work precisely!! Thank u
Hi hari hru
what an explanation sir...
you are a fabulous teacher.
I was struggling so much in this chapter after hearing this video it was very easy to solve work and time problems and cracked an exam real easily......thank you so much sir!!!
Q6. Simple way: Find 1 day work by 3 men (1/2), 1 day work by 1 men (1/6) similarly 1 day work by 4 boys (1/4), 1 day work by 1 boy (1/24). then find 1 day work by 8 men (8/6) and 1 day work by 8 boys (8/24) add them get answer (3/5) .......lol
thnx
Each and every video of yours is very helpful and can get easily understood by the simplest concepts.
Thanks, Komal!
All the best everyone for your exams!
I have been coming across all, at any point I haven't felt bored, all the way it's exciting and you making tough topics, easy!! Btw Love your cliches asf!! If I would pass the aptitude part in my college placemnts, full credits goes to yu. Keep up your adorable teaching as well as admirable work.
These topics in the quantitative aptitude playlist are sufficient for placement test?
In 2024 watching
For the 1st question..
Work Efficiency => a: b= 5:1
Time efficiency=>a:b= 1:5
So b takes 60 more days to complete the work
So..b days - a days = 5x-1x = 60
=> 4x=60 =>x = 15
So b= 5x => 5*15=75 and a= 75-60= 15... thats it...let me know if u got any doubt...
@@mixedbyhals1329 tell me if im wrong...and clarify if u are smart enough.. dont be a dumbass tryin to judge.!...and the answer is correct..im sure ur poor at math.. birdbrain!!😂😂
Hi sir..in qn no: 4 they asking time ? What but put only dayss
This lecture is simply superb it was so much better than coaching aptitude lectures
Sir:Solves a difficult sum
Also sir: See how easy it was !!!😊😊
See...this is how our brain works :)
SOLUTION OF THIS PROBLEM PLEASE:
A and B together can complete 75% of a work in 33 days while A, B and
C together can complete the whole work in 26 days. If ‘C’ is 12.5% more
efficient than B then find the time taken by A and C together to complete
70% of the work.
Really good question
I have solved it more than half and I know which steps I should take next but I am lazy rn to do this much calculation
For proof (total days required to work be done by A and B is 44 days, work done by c in one day is 9/572, work done by B in one day is 9/1.125*572 ....)
Calculate the rest by yourself 🥱
In 9th problem, calculation of A and B working together consumes 2hrs for the work (176/(96*80)). Final answer is 120/11.
Best in India... Thank you so much especially those who do not afford coaching class & for non Hindi speaking people
