a) Rs 1100.68

b) Rs 1194.68

c) Rs 1200.68

d) Rs 1294.68

correct answer is: b) Rs 1194.68

**Explanation**

Here,

Principal (p) = Rs 4600

Rate (r) = 8 % p.a.

Number of years (n) = 3

We know,

Amount = p\left[1+\left(\frac{r}{100}\right)\right]^n

So that,

4600\left[1+\left(\frac{8}{100}\right)\right]^3

\rightarrow\ 4600\left[\frac{100+8}{100}\right]^3

\rightarrow\ 4600{\times\left[\frac{108}{100}\right]}^3

\rightarrow\ 4600\times\frac{108}{100}\times\frac{108}{100}\times\frac{108}{100}

\rightarrow5794.68

\therefore Amount = Rs 5794.68

Now, Compound Interest (C.I.) = (A – P)

\therefore Compound Interest = Rs \left(5794.68-4600\right)

\rightarrow Rs 1194.68 **Ans:** Rs 1194.68 is the compound interest on Rs 4600 for 3rd year when the rate of interest is 8% p.a.
