3rd homework qn ku 44 ans varudhu anna
Total boys and girls = 432
Boys: Girls = 5:4
Boys (5/9)* 432 = 240; Girls 432-240 = 192
New boys added 12 and new girls added x
Boys = 240+12 = 252; Girls = 192+x
Ratio becomes 7:6
252/(192+x) = 7/6
x=24

Home work sum la 3rd sum...yaravadhu explain pannunga friends...
Total Students 432 now we have to use the first ratio 5:4 ratio to find the number of boys and girls.
Boys= 240 and girls = 192
12 boys joined newly, and add the number 240 and 12 = 252
now we don't know the girls, so we have to take 192 +x
252/192+x = 7/6
divide the numbers 252 and 7
36 x 6= 1(192+x)
216 = 192 +x
216 - 192 =x
24 = x
Therefore, the new girls are 24.
homework sum kudukkave illa sir 😅
description la iruku bro
Thanks for your kindness video sir
Sir 2 question u did wrong sir
It's correct. I think you saying that 36 is wrong. That is -63 + 99 = 36
Home work sir
Sir can u pls make a video in english
Already he teached in english also...
Anna 3rd question answer 36 varudhu anna
240boys and 192 girls
then add 12 to boys
252/192+x = 7/6
by cross multiplication
1512 = 1344+7x
168 = 7x
x= 24 (ans)
