Question

If 12 boys earn Rs. 840 in 7 days, what will 15 boys earn in 6 days?

Answer 1

Given,

Earning of 12 boys in 7 days =Rs. 840

So,1 boy in 7 days will earn =Rs.$\frac{840}{12}$

$=70$ rupees

1 boy will earn in 1 day =Rs.$\frac{70}{7}$

Rs.

$\therefore$15 boys will earn in 1 days$=15\times 10=150$ Rs.

$\frac{$ =6\times 150=900$}{}$

Hence, 15 boys will earn 900 Rs. in 6 days.
