Hope this answers the question

Answer 2

Answer:

Principal = Rs.20000

Rate r = 20% =0.20

No. of compounds per year n = 4

Time = 1 year

Formula : A = P(1+\frac{r}{n})^{nt}

Where A= Amount

P = Principal

r = rate of interest

n = No. of compounds

t = time

A = P(1+\frac{r}{n})^{nt}

A = 20000(1+\frac{0.2}{4})^{4}

A=24310.125

Compound interest = Amount - Principal = 24310.125-20000 = Rs.4310.125

Hence The compound interest is Rs.4310.125
