20 men can make a road for 50 km in 10 days in hown many days can 15 men make a road for 7km

1.87 days

Step-by-step explanation:

If it takes 20 men can make a road for 50 km in 10 days, by the unitary method,  1 man can make 50 km/20 in 10 days.

So 1 man can make 2.5 km in 10 days.

We then calculate for 15 men by multiplying the expression by 15

So, for 15 men, 15 × 1 man can make 2.5 km × 15 in 10 days/

So, 15 men can make 37.5 km in 10 days.

Since 15 men can make 37.5 km in 10 days, 15 men will make 1 km in 10/37.5 days.

So multiplying by 7,

15 men will make 7 × 1 km in 7 × 10/37.5 days

Thus 15 men will make 7 km in 1.87 days

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?
