The simple interest accrued on an amount of ₹2500 at the end of 6 years is ₹1875. What would be the simple interest accrued on an amount of ₹6875 at the same rate and for the same period? (Bank P.O., 2009)
Answer
Answer (as printed):
Explanation
P = ₹2500, T = 6 years, S.I. = ₹1875. ∴ Rate $=\left(\frac{100 \times 1875}{2500 \times 6}\right)\%=12\frac{1}{2}\%$. Now, P = ₹6875, T = 6 years, $R=12\frac{1}{2}\%$. ∴ S.I. $=₹\left(\frac{6875 \times 25 \times 6}{100 \times 2}\right)=₹5156.25$.
