UP Police Constable Exam Model Paper 4

Given:
Amount received is Rs. 5290 on certain sum of money at 15% for 2 years
Formula used:
Amount = p × (1 + r/100)${}^{\mathrm{n}}$
Compound interest = p × (1 + r/100)${}^{\mathrm{n}}$ - p
Calculation:
Let the sum of money invested is P
∴ 5290 = p × (1 + 15/100)${}^2$
⇒ P = Rs. 4000
Hence, option (1) is correct
