Question

25 men can do a piece of work in 32 days. How many days would 8 men take to do the same work​

Answer 1

Step-by-step explanation:

Days taken by 25 mens to do the work= 32

Days taken by 8 mens to do the work= x

32:x= inverse of 25:8

32:x::8:25

====> Product of extremes= 32×25

====> Product of means= 8x

8x=32×25

x=32×25/8

x=25×4

x=100 days or 3 months 10 days.
