The compound interest accrued in 2 years on a principal of Rs.15,800 is Rs.7716.72. What is the rate of interest p.c.p.a?
Answer : Option A
Explanation :
A = P(1+R/100)T
=> 15800 + 7716.72 = 15800(1+R/100)2
=> 23516.72 = 15800(1+R/100)2
=> 23516.72/15800 = (1+R/100)2
=> 148.84/100 = (1+R/100)2
=> 12.2/10 = 1+R/100
=> R/100 = 2.2/10
=> R = (2.2/10)*100
22% per annum
