Answer» GIVENAt what rate will the simple interest on 20000 for 4 years will be equal to the simple interest on 30000 for 3 years at 10% SOLUTIONIn first CASE
In SECOND case
According to the given condition The simple interest on 20000 for 4 years will be equal to the simple interest on 30000 for 3 years at 10%. (★) Simple interest = P×R×T/100 → 20000 × R × 4/100 = 30000 × 10 × 3/100 → 200 ×R × 4 = 300 × 10 × 3 → 800R = 9000 → R = 9000/800 → R = 90/8 = 11.25 % Hence, the required rate is 11.25 % |
