A person agrees to work for 30 days, on a condition that for every day's work he should receive ₹500, and that for every day's absence from work he should forfeit ₹100. At the end of the time he received ₹11,400. How many days did he work?
- A. 20
- B. 21
- C. 24 ✓
- D. 25
Correct Answer: C. 24
Explanation
Let the number of working days be x. The days absent will be 30-x. Equation: 500x - 100(30-x) = 11400 \implies 600x - 3000 = 11400 \implies 600x = 14400 \implies x = 24.
