Question

$10$ men can complete the construction of a wall in $8$ days. How many men are required to complete the same work in 'half of a day'?

• A. $160$
• B. $100$
• C. $120$
• D. $150$

Answer 1

Answer: (A)

$160$

Let $x$ men required to complete the work.

According to the question,

$M_1{D}_1=M_2{D}_2$

$10\times 8=x\times \frac{1}{2}$

$80=x\times \frac{1}{2}$

$x=160men$

Hence, this is the answer.
