Question : The interest accrued on INR 12,000 in two years, when interest is compounded annually, is INR 3,870. What is the rate of interest per annum?

Option 1: 12.5%

Option 2: 10%

Option 3: 20%

Option 4: 15%

Team Careers360 25th Jan, 2024

Correct Answer: 15%


Solution : Principal sum, $P$ = INR 12,000
Term, $n$ = 2 years
Compound interest = INR 3870
Let $R$ be the interest rate.
When compounded annually,
Compound interest = $P(1+\frac{R}{100})^n - P$
⇒ $3870 = 12000(1+\frac{R}{100})^2 - 12000$
⇒ $3870 + 12000 = 12000(1+\frac{R}{100})^2 $

Option 2: 360 cm2

Option 3: 330 cm2

= $\sqrt{169}$
= $13$ cm
Total surface area = lateral surface area + area of the base
= $\frac{1}{2}$ × perimeter of base × slant height + area
