Answer 1

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,

\begin{gathered}56\times 15=10\times x\\\\840=10x\\\\x=\dfrac{840}{10}\\\\x=84\end{gathered}

56×15=10×x

840=10x

x=

10

840

x=84

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