RRB NTPC · Question 42

A husband and wife earn Rs 45,000 and Rs 35,000 per month respectively. Each of them donates Rs 5,000 a month from their own share to an orphanage. After taking out the donations, the husband's income is what percentage of their combined income?

  1. 56.25%

  2. 50%

  3. 57.14%

  4. 53.33%

Show answer & explanation

Answer: (C) 57.14%

Explanation

After each gives Rs 5,000, the husband has 45,000 − 5,000 = 40,000 and the wife 35,000 − 5,000 = 30,000, a combined Rs 70,000. The husband's share = 40,000/70,000 × 100 ≈ 57.14%.
