Correct Answer: ₹$5,088$ / ₹$5,088$
CI $= 20000\left[(1.12)^2 - 1\right] = 20000 \times 0.2544 =$ ₹$5,088$. Option (a) is the trap — it is the simple interest ($20000 \times 0.12 \times 2$), missing the interest-on-interest of ₹$288$. / चक्रवृद्धि ब्याज $= 20000\left[(1.12)^2 - 1\right] = 20000 \times 0.2544 =$ ₹$5,088$। विकल्प (a) जाल है — वह साधारण ब्याज है ($20000 \times 0.12 \times 2$), जिसमें ₹$288$ का ब्याज-पर-ब्याज छूट गया है।
