Answer: C) ₹ 600

Key idea: Reading the question carefully

Three things to check before you compute:

1. **What's being asked?** Profit % needs CP and SP. SI needs P, R, T.
2. **What units are the inputs in?** Time in months → convert to years (divide by 12). Rate already per annum → leave it.
3. **What's the base of the percentage?** Profit/loss % is on COST price, not selling price. Discount % is on MARKED price, not on what you actually paid.
