1. Find the difference between compound interest and simple interest if P = ₹.4000, R= 5 p.c.p.a and N= 2 yrs.
Answers
Answer:
0.0185
Step-by-step explanation:
SIMPLE INTEREST = PRT / 100
= 7.4 × 5 × 2 / 100 = 0.74
COMPOUND INTEREST, A = P(1+R/100)^n
= 7.4 (1+5/100)^2 = 7.4 ×105/100 ×105/100 = 8.1585
CI = A-P = 8.1585-7.4 = 0.7585
DIFFERENCE
= 0.7585-0.74
=0.0185

Before, finding the answer. Let's find out on how we can find the answer.
- First, we must find the Compound interest by the formula of
Compound Interest = Amount - Principal
- Next, we must find the Simple Interest by the formula of
- At last, we must Subtract the Compound Interest and Simple Interest.

Given :
- Principal = Rs. 4000
- Rate = 5%
- Time = 2 years
To find :
- Difference between compound interest and simple interest.
Solution :
We know that,
Compound Interest = Principal - Amount
= Rs. 4000 - 4410
= Rs. 410
Hence, Compound Interest is Rs. 410.
Hence, Simple Interest is Rs.400
Difference = Compound Interest - Simple Interest
= Rs. 4410 - 400
= Rs. 4010
Hence, Difference is Rs. 4010.
