Q:

$i f \log \frac{a}{b} + \log \frac{b}{a} = \log (a + b), t h e n$

A) a + b = 1	B) a - b = 1
C) a = b	D) ab=1

Answer & Explanation Answer: A) a + b = 1

Explanation:

$i f \log \frac{a}{b} + \log \frac{b}{a} = \log (a + b), t h e n$

$\log (a + b) = \log (\frac{a}{b} \times \frac{b}{a}) = \log 1$

so, a+b=1

A) 216 sq.cm	B) 316 sq.cm
C) 416 sq.cm	D) 516 sq.cm

Answer & Explanation Answer: A) 216 sq.cm

Explanation:

Let the edge of the cube be a.

Q:

Find the cost of 96 shares of Rs. 10 each at $\frac{3}{4}$ discount, brokerage being 1/4 per share.

A) 912	B) 921
C) 920	D) 900

Answer & Explanation Answer: A) 912

Explanation:

Cost of 1 share = $R s . [(10 - \frac{3}{4}) + \frac{1}{4}] = R s \frac{19}{2}$

Cost of 96 shares = $R s . (\frac{19}{2} * 96)$ = Rs. 912.

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%
