Answer 2

Explanation:

Given :-

Principle = Rs. 256

Compound Interest = 100% per annum

Compound Interest is calculated quarterly

To find :-

Find the compound interest ?

Solution :-

Given that :-

Principle = Rs. 256

Compound Interest = 100% per annum

Compound Interest is calculated quarterly

So ,Total number of times the interest calculated per annum = 4

n = 4

Rate of interest per quarterly = 100%/4 = 25%

Given time = 1 year

We know that

Compound Amount = P[1+(R/100)]^n

On substituting these values in the above formula

=> A = 256[1+(25/100)]⁴

=> A = 256 [ 1+(1/4)]⁴

=> A = 256 [ (4+1)/4]⁴

=> A = 256 [ (5/4)⁴

=> A = 256(5×5×5×5)/(4×4×4×4)

=> A = 256×625/256

=> A = 625

Amount after 1 year = Rs. 625

We know that

Amount = Principle+ Interest

=> Compound Interest = Amount - Principle

=> CI = 625-256

=> CI = Rs. 369

Answer:-

The Compound Interest for the given problem is Rs. 369

Used formulae:-

• Compound Amount = P[1+(R/100)]^n

• Amount = Principle+ Interest

• P = Principle

• T = Time

• R = Rate of Interest

• A = amount

• n = number of times the interest calculated
