Question

find the simple interest on the sum of ₹1,200 for 1½ years of the rate of 15% per annum​

Answer 1

As per the data given in the question,

In the above question, it is given that,

The given amount is Rs.1200  

For the year $1\frac{1}{2}$years.

At the rate of 15%

Here we have to find the simple interest.

We have to use the formula of SI,

$SI=\frac{PRT}{100}$

Further substituting the value in the above equation we get,

$SI=\frac{1200\times 15\times1.6 }{100}$

$=288$

 Hence the SI for $1\frac{1}{2}$ years is 288 and the amount of Rs.1488.

Answer 2

Here we have to find the simple interest

Given: principal = Rs. 1200

         Time = 1.5 years

         Rate = 15 %

We will use the formula of simple interest

simple interest = ( P × R × T ) / 100

  putting the values in the above formula

Simple interest = ( 1200 × 15 × 1.5 ) / 100

                        = 270

Hence, the simple interest will be 270
