Question

If 15 men can reap a field in 28 days; In how many days can 5 men reap it?

• A. 20 days
• B. 80 days
• C. 84 days
• D. 82 days

Answer 1

The correct option is C 84 days

Let the required number of days be ‘x’. Here, if the number of men is less, then the number of days taken is more. So, it is a case of indirect variation.
$\therefore 15\times 28=5\times x\Rightarrow x=\frac{15\times 28}{5}=3\times 28=84days$
$\therefore$ 5 men will reap the field in 84 days.
