Question

10 men can lay a road of 75 km long in 5 days in his many days van 15 men lay a road of 45 km long​

Answer 1

Let me help you with this question.

Given that, 10 men can lay a road 75 km long in 5 days

Therefore,

75 / (10 x 5) = 75 / 50

75 / (10 x 5) = 15 / 10 km per man per day.

Now, we have to calculate the number of days in which 15 men lay a road 45 km long.

Let number of days be 'D'

Then,

45 / (15 x D) = 15 / 10

15 x D = 45 x 10/15

D = (3 x 10) / 15

D = 2

which shows that 15 men lay a road 45 km long in 2 days.

Hopefully it helps.

Thanks.
