Question

If 5 men can do a certain construction work in 14 days , then how long will 7 men take to complete the same construction work?

Answer 1

Step-by-step explanation:

5 men can do a construction in = 14 days

Therefore ,

1 man can do the work in = 14 × 5 days [ Since , one man takes longer time to complete the same piece of work ]

Therefore ,

7 men will complete the work in = 14 × 5 / 7 days

= 2 × 5 days

= 10 days ( Answer )
