A is 20% less efficient than B. If A can complete a work in 15 days, in how many days will B complete it? MCQ with Answer and Explanation

Explanation:
8 Men = 12 Women => 1 Man = 1.5 Women. 6 men + 11 women = 6 * 1.5 + 11 = 9 + 11 = 20 women. Since 12 women do the work in 25 days, 20 women will do it in (12 * 25) / 20 = 300 / 20 = 15 days.

Explanation:
Percentage completed = (6/30) × 100 = 20.0%.

Explanation:
A share = (1/24) / (1/24+1/22) ×100 = 47.83%.
