Question
Rs.13000 was invested for 2 years in scheme A which
offers compound interest at 10% per annum. What approximate interest earned on investing the amount obtained from scheme A again in the same scheme for 2 years.Solution
R= 10% Time = 2 yr. (Compound interest) Total interest (Rate%) = 10+10+(10×10)/100 =21% amount obtained from scheme A = 13000 ×(121/100) Interest at earned on investing the amount obtained from scheme A again in the same scheme for 2 years = 13000 ×(121/100) × (21/100) = Rs. 3303.30
