Q:

Find the odd number in the given number series?

14, 27, 105, 525, 4993

A) 27	B) 105
C) 525	D) 4993

Answer & Explanation Answer: C) 525

Explanation:

The given number series is 14, 27, 105, 525, 4993

14

14 x 2 - 1 = 27

27 x 4 - 3 = 105

105 x 6 - 5 = 625 (not 525)

625 x 8 - 7 = 4993

Hence, the odd man or number in the given number series is 525.

Q:

A certain sum of money amounts to Rs 1008 in 2 years and to Rs 1164 in 3 ½ years. Find the sum and the rate of interest.

A) 800, 14%	B) 800, 13%
C) 800, 12%	D) 800, 19%

Answer & Explanation Answer: B) 800, 13%

Explanation:

S.I. for 1 ½ years = Rs (1164 - 1008) = Rs 156 .

S.I. for 2 years = Rs (156 x $\frac{2}{3}$ x 2)= Rs 208.

Therefore, Principal = Rs (1008 - 208) = Rs 800.

Now, P = 800, T= 2 and S.I. = 208.

Therefore, Rate = (100 x S.I.) / (P x T) = [ (100 x 208)/(800 x 2)]% = 13%

61, 66, 83, 121, 185

A) 185	B) 121

Answer & Explanation Answer: B) 121

Explanation:

Given number series is 61, 66, 83, 121, 185

Here the given series follows a pattern that,

$61 61 + (2^{2} + 1) = 66 66 + (4^{2} + 1) = 83 83 + (6^{2} + 1) = 120 (not 121) 120 + (8^{2} + 1) = 185$

Hence, the odd man in the given series is 121.
