Amir saves 32% of his monthly salary. If he spends Rs. 27200, then find his savings?

Correct answer: D. 12800

  • A. 15400
  • B. 14300
  • C. 13200
  • D. 12800

Explanation

If Amir saves 32% of his salary, he spends the remaining 68%. Therefore, 68% of salary = Rs. 27200, giving salary = Rs. 27200 ÷ 0.68 = Rs. 40000. Savings = 32% of Rs. 40000 = 0.32 x Rs. 40000 = Rs. 12800. The likely trap is Rs. 13200, which comes from using an incorrect remaining percentage.
