Question

2. If 30 men can do a piece of work in 15 days, in
how many days will 25 men do it?​

Answer 1

Answer:

Inverse proportion

Step-by-step explanation:

men               days

30                  15

25                  y2

by inverse proportion

x1 x y1 = x2 x y2

30 x 15 = 25 x y2

y2 = 450/25

y2 = 18

Ans:- 18 days to finish the work by 25 men.

Answer 2

Answer:

If 30 men do a piece of work in 15

so 1 men can do it in 1/2 days

25 men can do it in 25*1/2 days

or in 12 and 1/2 days
