Answer 1

Given :

Principal, (P) = Rs.40

Rate, (R) = 10% p.a

Time, (T) = 4 years

Explanation :

As we know that Formula of the Simple Interest & compound Interest:

Simple Interest = principal×Rate × Time/100

A = P(1 + R/100)^n

According to the question :

➝ Simple Interest = PRT/100

➝ Simple Interest = 40 × 10 × 4/100

➝ Simple Interest = 1600/100

➝ Simple Interest = Rs.16

&

➝ A = P(1 + R/100)^n

➝ A = 40(1 + 10/100)⁴

➝ A = 40(1 + 1/10)⁴

➝ A = 40(10 + 1/10)⁴

➝ A = 40(11/10)⁴

➝ A = 40 × 11/10 × 11/10 × 11/10 × 11/10

➝ A = 585640/10000

➝ A = Rs.58.56

As we know that Compound Interest :

➝ C.I = Amount - Principal

➝ C.I = Rs.58.56 - Rs.40

➝ C.I = Rs.18.56

Now,

Difference = C.I - S.I

Difference = Rs.18.56 - Rs.16

Difference = Rs.2.56
