Correct Answer - Option 2 : 24 days
Given:
3 men and 6 women complete a work in 4 days.
The efficiency of men is twice the efficiency of women.
Formula used:
Total work = Efficiency × Time
Calculation:
According to the question, we have
The efficiency of man = 2 × The efficiency of woman
So, (The efficiency of man/The efficiency of woman) = 2 : 1
Now, according to the formula, we have
Total work = (3 × Efficiency of a man + 6 × Efficiency of a woman) × 4
⇒ (3 × 2 + 6 × 1) × 4
⇒ 12 × 4
⇒ 48
So, time is taken by 2 women to completes the same work = {48/(1 × 2)} days
⇒ 24 days
∴ 2 women can complete the work in 24 days.
