If 3 men or 6 women can do a piece of work in 16 days, in how many days can 8 men and 8 women do the same piece of work? यदि 3 आदमी या 6 औरतें एक काम को 16 दिनों में कर सकते हैं, 8 आदमी और 8 औरतें उसी कार्य को कितने दिनों में कर सकते हैं ?
-
4 days/दिन
-
5 days/दिन
-
3 days/दिन
-
2 days/दिन
A
Correct answer
Explanation
From the given information, 3 men's work = 6 women's work, so 1 man = 2 women. The total work is 3 × 16 = 48 man-days. Converting 8 men and 8 women to men: 8 men + 4 men = 12 men total. Days needed = 48/12 = 4 days. The key is converting women to equivalent men using the rate relationship.
