Select the option in which the numbers share the same relationship as that shared by the given pair of numbers.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding/deleting/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.)
13 : 55
23 : 105
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 31 : 145.
13 : 55 ⇒ 13 × 5 - 10 ⇒ 65 - 10 = 55
23 : 105 ⇒ 23 × 5 - 10 ⇒ 115 - 10 = 105
Similarly, 31 : 145 ⇒ 31 × 5 - 10 ⇒ 155 - 10 = 145
