Answer» Compound interest for 2nd year can be given as ⇒ CI for 2nd year = y{(1 + 10/100)2 – (1 + 10/100)} = 1200 ⇒ 1200 = y(1.12 – 1.1) ⇒ 1200/0.11 = y ⇒ y = Rs. 10909.1 Compound interest for 4th year can be given as ⇒ CI for 4th year = y{(1 + 10/100)4 – (1 + 10/100)3} ⇒ CI for 4th year = 10909.1(1.14 – 1.13) = 10909.1 × 0.1331 ⇒ CI for 4th year = Rs. 1452 ∴ Interest for 4th year is Rs. 1452 |
