Question

20 boys are required to complete a work in 100 days. How many boys are required to complete that work in 5 days?
a) 200
b) 250
c) 300
d) 400​

Answer 1

Answer:

Let the number of boys be x.

x = (100 × 20)/5

400 boys are required to complete that work in 5 days

Answer 2

100 days × 20 boys = 5 days × X boys

100×20 = 5 × X boys

2000 = 5 × X boys

X boys = 2000 / 5

X boys = 400

Ans 400 boys
