Question 129

The time in which 80,000 ambunts to 92,610 at 10% p.a. at compound interest, interest being compounded semi annually is :

Solution

Given that Rs 80000 becomes Rs 92610 at 10% per annum .

semi-annual Rate become = $$\frac{10}{2}$$ = 5%

Let number of semi-annual cycles required = T

So Using ,

Compounded Amount = P$$(1+\frac{R}{100})^T$$

92610 = 80000$$(1+\frac{5}{100})^T$$

T = 3 semi annual cycles = 1.5 years
