GIVEN:- 8 men complete the same work as 12 women. In how many days will 15 women complete the same work which 12 men complete in 20 days?*

1️⃣ 21

2️⃣ 20

3️⃣ 24

4️⃣ 27

Answer:-

we have,

→ 8M = 12W

→ M / W = 12/8

→ M/W = 3/2

Let

a man efficiency is 3X units and woman is 2X units .

so,

→ Total work done by 12 men in 20 day = (12 * 3x) * 20 units

and,

→ 15 women efficiency per day = 15 * 2x = 30x units .

then,

→ Time taken to complete same work = (12 * 3x * 20) / 30x = 24 days (Option 3) (Ans.)
