1. Rs. 2400
2. Rs. 1600
3. Rs. 1000
4. Rs. 1200

Answer 1

Correct Answer - Option 2 : Rs. 1600

Given:

10 Men in 5 days earned Rs. 800

Women are twice as efficient as men 

Concept used:

If x person in n days earn Rs. y, then 1 person will earn in 1 day Rs y/(x × n) 

Calculation:

10 men earned in 5 days = Rs. 800

1 man will earn in 1 day = 800/(5 × 10)

1 man will earn in 1 day = 160/10 = Rs. 16

As women are twice as efficient as men so woman will earn twice of what man would earn.

1 woman will earn in 1 day = 2 × 16 = Rs. 32

5 woman will earn in 10 days = 5 × 10 × 32 = 1600

∴ 5 woman will earn Rs. 1600 in 10 days
