Question

Find the simple interest on a certain sum is $Rs.1200$ in $3$ years at the rate of $10\%$ per annum.

• A. $Rs.360$
• B. $Rs.350$
• C. $Rs.390$
• D. $Rs.320$

Answer 1

Answer: (A)

$Rs.360$

We have,

$P=Rs.1200$

$T=3years$

$R=10\%$

$S.I=?$

We know that

$S.I=\frac{PRT}{100}$

So,

$S.I=\frac{1200\times 10\times 3}{100}$

$S.I=12\times 10\times 3$

$S.I=Rs.360$

Hence, this is the answer.
