Answer: A) Gown Explanation: A Christian Priest wears cassock while a Graduate wears gown.   Hence, Cassock : Priest :: Gown : Graduate.

A book is consists of various chapters, so as the Organization consists of various departments. Therefore if Book is to chapter so organization is to department.   Hence, Book : Chapter :: Organisation : Department.

A Clock has 3 hands i.e, an Hour hand, a Minute hand and a Seconds hand.

From the assumption and trial and error method, last three digits sum must leave the same digit as the answer. It is possible only if the answer must be units digit number leaving tens digit as carry. And the possible 3rd digit is 5. Since 5 + 5 + 5 = 15  Now, 2nd step is  1 + x + x + x = 5 => 3x = 4 It is possible with x = 8. 8 + 8 + 8 + 1 = 25 leaving 2 as carry.  Now, 3rd step is 2 + x + x + x = 5 => x = 1   Hence, the three dgits are 1, 8, 5. 185 + 185 + 185 = 555.

Answer: C) Both A & B Explanation: Brightness of bulb depends on both voltage and current. The brightness depends on power. Since we know that  Power (P) = Voltage x Current = V I So whether you increase the current or the voltage the brightness will increase.   Example Illustration:  If you connect a long bulb and a round bulb in series, the long bulb glows but the round bulb does not. Both of them have the same current flowing through them (they are in series) but the long bulb has a greater voltage across it because it has more resistance (even though V= IR is not obeyed exactly, voltage drop does depend on the resistance). If you connect a round bulb and a long bulb in parallel, however, it is the round bulb that is brighter because now the voltage across both bulbs is the same but the current is larger through the round bulb (smaller resistance).   Hence, the brightness of a bulb depends on power i.e, both voltage and current.

Answer: D) 8 Explanation: Given number series follows a pattern that, 2 2 x 1.5 + 1 = 4 4 x 1.5 + 1 = 7 (not equal to 8) 7 x 1.5 + 1 = 11.5 11.5 x 1.5 + 1 = 18.25 18.25 x 1.5 + 1 = 28.375   Hence, the odd number in the given number series is 8.
