boys = 34
Step by step explaination
50 girls and boys
41rs given to them
a boy get 90 paise
and 65 paise per girl gets
let the number of boys be X and girls be 60 - X
we kno that 1 Rs = 100 paise
90paise = 0.9Rs
65paise = 0.65Rs
according to question
0.9 (X) + 0.65 (50-x) = 41
0.9x + 32.5 - 0.65x = 41
0.9x + 0.65x = 41 - 32.5
0.25x = 8.5
x = 8.5 / 0.25
x = 34
therefore number of boys= 34
