मिलकर कितने समय में पूरा कर लेंगे?

Answer 1

Answer:

2 men = 3 women

1 men = 3/2 women

so 4 men = 3/2 × 4 women = 6 women

now the problem is

3 women can do a work in 40 hours

what time will 4 men and 9 women take to complete the work

it means that 4 men = 6 women

so 4 men and 9 women = 6 women + 9 women = 15 women

so the solution is,

3 women= 40 hours

1 women = 40 × 3 = 120 hours

15 women = 120/15 hours = 8 hours
