Question

28 men take one week to complete 7/8 part of particular piece of work. If the remaining work is to be completed in a week, then how many men will be required

Answer 1

Assume that all women and men are created equal & no task needs large members. If 28 men could complete 7/8 then divide 7 to get a perfect number needed for the remaining 1/8.

That is, 28/7= 4 men. Addition of people to some job might slow down the work progress as they get in each other’s way and other restrictions such as access to materials, availability and management will reduce the work.

Answer 2

28 men take one week to complete 7/8 of the work (Given)

Find the amount of the remaining work:

Remaining work = 1 - 7/8 = 1/8

Find the number of men needed to finish 1/8 of the work:

7/8 of the work = 28 men

1/8 of the work = 28 ÷ 7 = 4 men

Answer: 4 men is needed to complete the remaining work in a week
