Solution Let the amount work done by a woman in a day be W. So, the amount of work done by a man in a day is W/2. And the amount of work done by a child in a day is W/4 So, the amount of work done by 3 men, 4 women and six children in a day is 3W/2 + 4W + 6W/4 = 7W. Hence, 7 women can complete this work in 7 days. So, the correct answer is option (b)
A piece of work can be done by 6 men and 5 women in 6 days or 3 men and 4 women in 10 days. It can be done by 9 men and 15 women in how many days ?
Answer: Option A Explanation: To calculate the answer we need to get 1 man per day work and 1 woman per day work. Let 1 man 1 day work =x and 1 woman 1 days work = y. => 6x+5y = 1/6 and 3x+4y = 1/10 On solving, we get x = 1/54 and y = 1/90 (9 men + 15 women)'s 1 days work = (9/54) + (15/90) = 1/3 9 men and 15 women will finish the work in 3 days Answer: Option D Explanation: A+B 1 day work = 1/8 B+C 1 day work = 1/12 A+B+C 1 day work = 1/6 We can get A work by (A+B+C)-(B+C) And C by (A+B+C)-(A+B) So A 1 day work = \begin So A and C can together do this work in 8 days Answer: Option A Explanation: In this type of question, where we have one person work and together work done. Then we can easily get the other person work just by subtracting them.

[Solved] 3 men, 4 women and 6 children can complete a work in 7 days.
Given ∶ Time taken by 3 men, 4 women, 6 children to complete the work = 7 days. A woman does double work compare to a man and a child does half work compare to a man. Ratio of efficiency of man and woman = 1 ∶ 2, Ratio of efficiency of child and man = 1 ∶ 2 Calculation ∶ Ratio of efficiency of man, woman and child = 2 ∶ 4 ∶ 1 Total work = (3 man + 4 woman + 6 child) × 7 days = (3 × 2 + 4 × 4 + 6 × 1) × 7 = 28 × 7 = 196 Number of women necessary to complete to the work in 7 days = 196/(4 × 7) = 7
