Question

A certain number of men can finish a work in 50 days. If there are 7 more men, the work can be completed 10 days earlier. How many men were originally there?

Answer 1

Answer: 35 men

Step-by-step explanation:

Let ' x ' be the number of men :

x men = 50 days

x + 7 men = 40 days

On cross multiplying :

40x = 50x + 350

50x - 40x = 350

10x = 350

x = 350 / 10

x = 35 men

Therefore, originally there were 35 men...
