Question

Find the simple interest on a principal of Rs. 3200 at 8% per annum for a period of 4 years.​

Answer 1

Answer:

S O L U T I O N :

Given :

Principal, (P) = Rs.10000

Simple Interest, (SI) = Rs.3200

Rate, (R) = 8% p.a

Explanation :

As we know that formula of the Simple Interest :

S.I = Principal × Rate × Time/100

According to the question :

➝ Simple Interest = PRT/100

➝ Time = S.I × 100/P × R

➝ Time = 3200 × 100/10000 × 8

➝ Time = 320000/80000

➝ Time = 32/8

➝ Time = 4 years

Thus,

The time or period of the interest will be 4 years .

Answer 2

Simple interest as per given dar is Rs. 1024.

Given - Principal, rate and time

Find - Simple interest

Solution - The simple interest can be calculated by the formula -

Principal*rate*time/100

Simple interest = 3200*8*4/100

Performing multiplication and division

Simple interest= 1024

Hence, the simple interest as per given data is Rs. 1024.
