CorrectNot quiteAnswer B

Correct answer: B

Rise this year = ₹18,000, so rate = $\frac{18000}{144000} \times 100 = 12.5\%$ .
Next year = $162000 \times 1.125 = ₹1{,}82{,}250$ .

Worth noting

Adding the same ₹18,000 again gives ₹1,80,000 — the same PERCENTAGE rise on a bigger base is a bigger rupee rise.
