Question

39. A certain number of men complete a
piece of work in 60 days. If there were
8 men more, the work could be finished
in 10 days less. How many men were
originally there?​

Answer 1

Answer:

51

Step-by-step explanation:

Let the original number of people be x

original number of people = x

number of people added = 8

new number of people = x + 8

time taken by x = 60 days

time taken by x + 8 = 10 days less = 60 - 10 = 50 days

Therefore,

x + x + 8 = 60 + 50

2x + 8 = 110

2x = 110 - 8

2x = 102

x = 102/2

x = 51

Therefore,

The original number of people is 51.
