Answer:
Given details are,
Rate = 15 % per annum
Compound Interest (CI) – Simple Interest (SI)= Rs 283.50
Time (t) = 3 years
By using the formula,
P [(1 + R/100)n – 1] – (PTR)/100 = 283.50
P [(1 + 15/100)3 – 1] – (P(3)(15))/100 = 283.50
P[1.520 – 1] – (45P)/100 = 283.50
0.52P – 0.45P = 283.50 0.07P = 283.50
P = 283.50/0.07 = 4000
∴ The sum is Rs 4000.Read more on
