Q:

A water tank is two-fifth full.Pipe A can fill a tank in 10 minutes and pipe B can empty it in 6 minutes.If both the pipes are open,how long will it take to empty or fill the tank completely?

A) 6 min.to empty	B) 6 min.to fill
C) 9 min.to empty	D) 9 min.to fill

Answer & Explanation Answer: A) 6 min.to empty

Explanation:

Clearly,pipe B is faster than pipe A and so,the tank will be emptied.

part to be emptied = 2/5

part emptied by (A+B) in 1 minute= $(\frac{1}{6} - \frac{1}{10}) = \frac{1}{15}$

$\frac{1}{15} : \frac{2}{5} : : 1 : x$

$\frac{2}{5} * 15 = 6 m i n s$

so, the tank will be emptied in 6 min

61, 66, 83, 121, 185

A) 185	B) 121
C) 83	D) 66

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.

Q:

Pick the odd man out of the folowing number sequence?

123 112 133 112 143

A) 143	B) 122
C) 133	D) 112

Answer & Explanation Answer: B) 122

Explanation:

Here the given series is 123 112 133 112 143

It follows a pattern that,

123

123 - 11 = 112

112 + 21 = 133

133 - 31 = 102 (not 122)

102 + 41 = 143

Hence, the odd man in the given number sequence is 122 instead of 102.
