We need the total expenditure on Utilities and Marketing.
- Step 1: Identify percentages. Utilities = 15%, Marketing = 10%.
- Step 2: Calculate amounts. Total = 200 crores.
- Utilities: \( 0.15 \times 200 = 30 \) crores.
- Marketing: \( 0.10 \times 200 = 20 \) crores.
- Step 3: Sum.
\[
30 + 20 = 50 \text{ crores}
\]
- Step 4: Verify. Total percentages: \( 15 + 10 = 25% \). \( 0.25 \times 200 = 50 \). Correct.
- Step 5: Check options.
- (a) 50: Correct.
- (b) 55: Incorrect.
- (c) 60: Incorrect.
- (d) 65: Incorrect.
- Step 6: Alternative metho(d) 10% = 20 crores, so Utilities = \( 1.5 \times 20 = 30 \), total = \( 30 + 20 = 50 \).
Thus, the answer is a.
