This question was previously asked in
RRB Technician 2026 Grade 3 Question Paper (7-Oct-2026) (Shift 3)
The correct answer is

₹3481

Amount = \( P\left(1+\frac{R}{100}\right)^n \).

\( A=2500\left(1+\frac{18}{100}\right)^2=2500\times(1.18)^2=2500\times1.3924 \).

\( A=3481 \).

Hence, the amount after 2 years will be ₹3481.
