A parent invested ₹3,00,000 in a UK education bond at 8% CI for 3 years. Afterward, due to devaluation, the return (in ₹) is converted and reinvested at 10% CI annually in India for 2 more years. If the amount after UK bond matures becomes ₹3,78,000, what will be the amount after 5 years?

  1. ₹4,55,000

  2. ₹4,57,380

  3. ₹4,60,000

  4. ₹4,50,000

Answer: B

Solution

Solution: The amount reinvested in India is ₹3,78,000. For 2 years at 10% compound interest, \(A=P(1+\frac{r}{100})^n\). Thus, \(A=378000(1+\frac{10}{100})^2=378000(1.1)^2\) = ₹4,57,380. Trick: Use the stated maturity amount as the principal for the second investment period.
