Here it is given that,
- Principal = Rs. 4000
- Time = 2 years
- Rate of interest = 10%
➢ We have to find the difference between the compound interest and the simple interest.
Now,
Now,
Now,
- C.I = Amount - Principal
⟹ C.I = 4840 - 4000
⟹ Compound interest = Rs. 840
Now,
➢ Difference between C.I and S.I :
⟹ 840 - 800
⟹ Rs. 40
- Therefore, the answer is Rs. 40

Given :-
- Principle = Rs. 4000
- Time = 2 years
- Rate = 10%
To Find :-
Find the difference between the compound interest and the simple interest
Solution :-
We know that
SI = PRT/100
CI = P(1 + R/100)ⁿ - P
For SI
SI = 4000 × 10 × 2/100
SI = 40 × 10 × 2
SI = 400 × 2
SI = Rs. 800
For CI
CI = P(1 + R/100)ⁿ - P
CI = 4000(1 + 10/100)² - 4000
CI = 4000(100 + 10/100)² - 4000
CI = 4000(110/100)² - 4000
CI = 4000(11/10)² - 4000
CI = 4000 × 121/100 - 4000
CI = 40 × 121 - 4000
CI = 4840 - 4000
CI = Rs. 840
Now
Difference = CI - SI
Difference = 840 - 800
Difference = Rs. 40
