Question

. If 12 boys can earn US$ 2,400 in 5 days, then how many boys can earn US$ 4, 200 in 21 days?

Answer 1

I hope its five.


when we divide 2400 by 5days we get 480 dollars

Then its 480 dollars earnt by 12 boys in one day

Then amount earnt by one boy in one day is 480/12=40dollars

Then for 21 days one boy will earn 21*40=840dollars

So the sum of dollars is 4200 dollars

Then number of boys = 4200/840=5 boys

THERE'S UR ANSWER IT IS FIVE !!!
