Answer:

If 4 men take 10 days, then it means 1 men will take 40 days. So from this you can calculate 5 people will take 8 days.

Or

We have a formula for this.

As you know, no of days will be in indirect proportion to no of men for a job, because if we increase count of men then days reduce.

So the formula will be

10/x=5/4

Where x is no of days by 5 men.

Hope this will be helpful to understand the concept of such type of questions. :)

a. 5

b. 7

c. 6

d. 8

[tex] \huge \pink{EXPLANATION}[/tex]

4 men × 10 days ÷ 8 days

  • 4 × 10 = 40
  • 40 ÷ 8 = 5

Therefore 5 men can do the same job in 8 days
