The interest on a certain deposit at 4.5\% p.a. is ₹ 202.50 in one year. How much will the additional interest in one year be on the same deposit at 5\% p.a. ?
(a) ₹ 20.25
(b) ₹ 22.50
(c) ₹ 25
(d) ₹ 42.75
Answer Explanation S.I. $=₹ 202.50, R=4.5 \%, T=1$ year. Principal $=₹\left(\frac{100 \times 202.50}{4.5 \times 1}\right)=₹ 4500$. Now, $P=₹ 4500, R=5 \%, T=1$ year. S.I. $=₹\left(\frac{4500 \times 5 \times 1}{100}\right)=₹ 225$. ∴ Difference in interest $=₹(225-202.50)=₹ 22.50$.
