Mohan credits 15% of his salary into his bank and spends 30% of the remaining amount on household articles. If cash in hand is Rs. 2,380, what is his salary?
Answer and explanation
Correct answer C
The correct choice is: “Rs. 4000”
Let the salary be S. After banking 15%, he has 0.85S. He spends 30% of this, so 70% remains: 0.7 × 0.85S = 0.595S. So 0.595S = 2380, which gives S = 2380 ÷ 0.595 = Rs. 4,000.
Check: 15% of 4000 = 600 banked, leaving 3400; 30% of 3400 = 1020 spent, leaving 2380.
