Solution
Principal (P) = Rs.15000
Rate (R) = 6% p.a.
Period (n) = 5 years
first year:
Interest for the first year =`("PRT")/100`
`=(15000xx6xx1)/100`
= Rs.900
∴ Amount for the first year = Rs.15000 + 900
= Rs.15900
Second year:
Principal (P) = Rs.15900
Rate (R) = 6% p.a.
Time take = 1 years
Simple Interest for the second year =`(15900xx6xx1)/100`
= 159 x 6
Simple Interest = Rs. 954
Compound interest = Rs. 954
