Question

Find the interest and the amount, respectively on Rs. $750$ in $3$ years $4$ months at $10$% per annum.

• A. Rs.$225$ and Rs.$1,000$
• B. Rs.$250$ and Rs.$1,000$
• C. Rs.$250$ and Rs.$1,150$
• D. Rs.$250$ and Rs.$1050$

Answer 1

The correct option is B Rs.$250$ and Rs.$1,000$

Interest $\left(I\right)=\frac{PNR}{100}$
Given, $P=Rs.750$

N = 3 years 4 months = $3\frac{4}{12}years=\frac{10}{3}years$
$R=10$ %
So, $I=\frac{750\times \frac{10}{3}\times 10}{100}=Rs.250$
Now, Amount = Principal + Interest = $Rs.750+Rs.250=Rs.1000$
