Question

28. If 5 men or 9 women can finish a piece of
work in 19 days, 3 men and 6 women will
do the same work in​

Answer 1

Step-by-step explanation:

Given:-

5 men or 9 women can finish a piece of work = 19 days

Formula Used:-

(M1 × D1)/W1 = (M2 × D2)/W2

Calculation:

5 Men = 9 women

1 men = (9/5) women

3 Men = 3 × (9/5) women = (27/5) women

So work done = 3 Men and 6 Women

⇒ 27/5 + 6 = 57/5

Let the day of complete piece of work 3 men and 6 women be X

⇒ (9 × 19)/W1 = [(57/5) × X]/W2

Here work is same so W1 = W2

⇒ 9 × 19 = 57X/5

⇒ X = 3 × 5 = 15

∴ The 3 men and 6 women will do the same work in 15 days.

hope this helps you ☺️
