Q:

A natural number when increased by 12 equals 160 times its reciprocal. Find the number?

A) 20	B) 12
C) 8	D) 4

Answer & Explanation Answer: C) 8

Explanation:

Let the required number be 'p'.

From the given data,

p + 12 = 160 x 1/p

=> p + 12 = 160/p

=> p(p + 12) = 160

=> P^2 + 12p - 160 = 0

=> p^2 + 20p - 8p - 160 = 0

=> P(p + 20) - 8(p + 20) = 0

=> (p + 20)(p - 8) = 0

=> p = -20 or p = 8

As, given the number is a natural number, so it can't be negative.

Hence, the required number p = 8.

A bottle is sold at a loss of 9%. Had it sold for Rs. 15 more, a profit of 25/2% would have gained. What is the cost price of the bottle (approx)?

A) Rs. 32	B) Rs. 35
C) Rs. 36	D) Rs. 33

Answer & Explanation Answer: B) Rs. 35

Selling price of the bottle = Rs. 100 - Rs. 9 = Rs. 91

Then, from the given data,

=> 112 (1/2) - 91 = 15

=> 21 (1/2) = 15

=> 43 = 15

Then 100 = ?

1500/43 = 34.885 =~ 35

Hence, the cost price of the bottle = Rs. 35
