Q:

An amount of 5,000 is invested at a fixed rate of 8 per cent per annum. What amount will be the value of the investment in five years time, if the interest is compounded annually

A) 7346.64	B) 8346
C) 3456	D) 4567

Answer & Explanation Answer: A) 7346.64

Explanation:

The only part of this type of calculation that needs particular
care is that concerning the interest rate. The formula assumes that
r is a proportion, and so, in this case:
r = 0.08
In addition, we have P = 5,000 and n = 5, so:
V = P(1 + r)5 = 5,000 x (1 + 0.08)5 = 5,000 x 1.469328 = 7,346.64
Thus the value of the investment will be 7,346.64

Q:

A man bought 20 shares of Rs. 50 at 5 discount, the rate of dividend being 13 $\frac{1}{2}$ . The rate of interest obtained is:

A) 13%	B) 12
C) 15%	D) 16%

Answer & Explanation Answer: C) 15%

Explanation:

Investment = Rs. [20 x (50 - 5)] = Rs. 900.

Face value = Rs. (50 x 20) = Rs. 1000.

Dividend = $R s . (\frac{27}{2} * \frac{1000}{100}) = R s . 135$

Interest obtained = $\frac{135}{900} * 100$ % = 15%
