Raees credits 15 % of his salary in this fixed deposit account and spends 30 % of the remaining amount on groceries if the cash in hand is Rs. 2380, what is his salary?

Correct answer: B. Rs. 4000

  • A. Rs. 3500
  • B. Rs. 4000
  • C. Rs. 4500
  • D. Rs. 5000

Explanation

After crediting 15% to the fixed deposit, 85% of the salary remains; spending 30% of this leaves 70% x 85% = 59.5% of the salary in cash. Therefore, 0.595 x salary = Rs. 2,380, giving salary = Rs. 2,380 / 0.595 = Rs. 4,000. Option a, Rs. 3,500, usually comes from subtracting 15% and 30% directly and mishandling the fact that groceries are 30% of the remainder.
