Question

the amount of interest for a certain sum at 5.5% annual rate of interest for one year is RS 676.5% how much interest will be less on the same sum at 5% annual rate of interest for one year?_(a) 55.5 (b) 61.5 (c) 56.25 (d) 53.25

Answer 1

56.25 was annual rate of interest for one year

Answer 2

Answer:

Rs. 61.5

Step-by-step explanation:

12300

Let the principal be x

Simple interest =  Rs. 676.5

Rate of interest = 5.5%

Time = 1 year

$Si =\frac{P \times R \times T }{100}$

$676.5=\frac{P \times 5.5 \times 1 }{100}$

$\frac{676.5 \times 100 }{5.5}=P$

$12300=P$

Now Rate of interest = 5 %

Time = 5

$Si =\frac{12300 \times 5 \times T }{100}$

$Si =615$

So, Difference between Simple Interests =676.5-  615 =Rs. 61.5

Hence interest will be less on the same sum at 5% annual rate of interest for one year by Rs. 61.5
