Question

Calculate the Simple Interest if the principal amount is Rs. 2000, the time period is 1 year and the rate is 10%. Also, calculate the total amount at the end of 1 year.​

Answer 1

Answer:

(i) Principal (P) = Rs 2000

Rate of interest (R) = 5% p.a.

Time (T) = 5 years

Simple interest = P×R×T100=2000×5×5100=Rs 500

(ii) Principal (P) = Rs 500

Rate of interest (R) = 12.5% p.a.

Time (T) = 4 years

Simple interest = P×R×T100=500×12.5×4100=Rs 250

Answer 2

Given that:-

Principal (P) = $2000$

Time (T) = $1$

Rate (r) = $10\%$

To find:-

The total amount ( A ) = ?

According to the formula of simple interest we have,

$S.I. = \frac{(Principal (P) \times Time (T) \times Rate (r))}{100}$

So, from the above values,

$S.I = \frac{2000\times 1 \times 10}{100}$

Simplifying it further, we get

=> $\frac{20000}{100}$

=> 200

So, the simple interest at the end of 1 year will be Rs. $200$.

For the amount after 1 year,

$A = P + S.I.$

So, $A = 2000+200 = 2200$

Hence, the total amount will be $Rs. 2200.$
