Question
On Rs. 6000 invested at a simple interest at the rate of
4% p.a., Rs. 2400 is obtained as interest in certain years. In order to earn Rs. 4800 as interest on Rs. 10,000 in the same number of years, what should be the rate of simple interest?Solution
S.I = (P ×R ×T)/100 2400 = (6000 × 4 × T)/100 T =240000/24000 T = 10 years Similarly, 4800 = (10000 × 10 × R )/100 R = 480000/100000 R = 4.8% per annum
