Question : In a field, 8 workers complete a task in 22 days. If this task is to be completed in 44 days, then how many workers will be required?
Option 1: 3
Option 2: 5
Option 3: 2
Option 4: 4
Correct Answer: 4
Solution :
Total workers ($M_1$) = 8
Time taken ($D_1$) = 22 days
Let the required workers ($M_2$) be $x$.
Time taken ($D_2$) = 44 days
We know that,
$M_1D_1= M_2D_2$
$⇒8\times22=x\times44$
$\therefore x=4$
Hence, the correct answer is 4.
