1

A man invested Rs.P in three different schemes – A, B and C in the ratio 2 : 1 : 3 respectively. He invested in scheme A at the rate of 10% p.a. at SI for 2 years, in scheme B at the rate of 5% p.a at C.I compounded annually for 2 years and in scheme C at the rate of 6% p.a at CI compounded half yearly for 1 year and received total interest of Rs. 6852. Find the value of P.

Solution & Explanation SI_A = 0.4x. CI_B = 0.1025x. CI_C = 0.1827x. Total = 0.6852x = 6852 => x=10000. P = 6x = 60000.

A man invested an amount in two schemes in the ratio of 2 : 3 at the rate of 20% p.a. and 10% p.a. on compound interest respectively. If the man gets a total interest of Rs. 1208 after two years from both the schemes, the find amount invested by man?

Solution & Explanation Effective rates: 20% CI 2yr = 44%, 10% CI 2yr = 21%. (2/5)P×0.44 + (3/5)P×0.21 = 1208 => P(0.176 + 0.126) = 1208 => 0.302P = 1208 => P=4000.

1500 rupees is invested in a scheme A at R% p.a. simple interest. Another amount (1500 - x) is invested in scheme B at 2R % p.a. simple interest. After 4 years, interest earned from scheme A is 25% less than that of scheme B. Find x.

Solution & Explanation SI_A = 1500×R×4/100 = 60R. SI_B = (1500-x)×2R×4/100 = 0.08R(1500-x). Given 60R = 0.75 × 0.08R(1500-x) => 60 = 0.06(1500-x) => 1000 = 1500-x => x=500.

A part of Rs. 38800 is lent out at 72% for six months. The rest of the amount is lent out at 5% p.a. after one year. The ratio of interest after 3 years from the time when first amount was lent out is 5 : 4. Find the second part that was lent out at 5%.

Solution & Explanation 0.36X / (0.1(38800-X)) = 5/4 => 1.44X = 19400 - 0.5X => 1.94X = 19400 => X = 10000. Second part = 38800 - 10000 = 28800.
