Question

6 persons can complete a piece of work in 35 days.



(a)

How many days will it take for 1 person to complete the work?
​

Answer 1

Answer:

The numberof men doing a work and the number of days taken are in inverse proportion.

Let the number of days taken by 28 men be a

Then, 35:a:: inverse ratio of 52:28

=>35:a=28:52

Applying the rule, product of extremes = product of means

35×52=a×28

a=

28

35×52

a=65

Hence, 28 men can do the work in 65 days
