Question

3 men and 5 women can do a work in 12 days. how long will 6 men and 5 women take to do it? ​

Answer 1

Men are 5/3 times as fast as Women.

3 Men = 5 Women,

3*12 = 3 men * 12 days = 36 man days.

5*12 = 60 women days.

5 women = 3 men, substitute into 2nd scenario,

6 Men + 3 Men = 9 Men.

3 Men take 12 days, therefore triple the men (9), third the time (4).

It will take 4 days.
