What is the compound interest on a sum of ₹12,000 for $2\frac{5}{8}$ years at 8% p.a., when the interest is compounded annually? (nearest to a rupee) |
₹2,642 ₹2,697 ₹2,712 ₹2,654 |
₹2,697 |
Interest for the first 2 years = 8% and Interest for last \(\frac{5 }{8}\) year = \(\frac{5 }{8}\) × 8% =5% So , Principal : Amount For 1st year 25 : 27 For 2nd year 25 : 27 For 3rd year 20 : 21 ---------------------------------------------------------- overall 12500 : 15309 ATQ, 12500R = 12000 1R = 0.96 CI = ( 15309 - 12500 )R = 2809R = 2809 × 0.96 = 2696.64 = 2697 ( approx )
