men should he employ?​

Answer 1

Answer:

15days------------------------56labours

10days------------------------??

(15/10)*56=84labours

Answer 2

28 more men he should employ.

Step-by-step explanation:

Since we have given that

Number of labourers to lay a road = 56

Number of days it requires = 15

If the number of days it required = 10

So, we need to find the number of labourers.

According to question, it becomes,

$56\times 15=10\times x\\\\840=10x\\\\x=\dfrac{840}{10}\\\\x=84$

Hence, 84-56 = 28 more men he should employ.
