E.g.13 – Operations on 13 such as adding/subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) 12 : 8 :: 28 : 16 :: 6 : ?
Option 1: 2
Option 2: 3
Option 3: 5
Option 4: 6

Question : Directions: Words given on the left side of (::) are related to each other by some Logic/Rule/Relation. Select the missing word/word pair on the right side of (::) from the given alternatives based on the same Logic/Rule/Relation. Watt : Power :: Ohm : ?
Option 1: Electrical Resistance
Option 2: Current
Option 3: Volume
Option 4: Force
Correct Answer: Electrical Resistance
Solution : Given: Watt : Power : Ohm : ?
Like, Watt is the S.I. unit of Power. Similarly, Ohm is the S.I. unit of Electrical resistance.
Hence, the first option is correct.
Question : Directions: Select the option that is related to the third number in the same way as the second number is related to the first number and the sixth number is related to the fifth number. 33 : 101 :: 39 : ? :: 35 : 107
Option 1: 117
Option 2: 119
