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 their 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.)
33 : 340
48 : 490
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 63 : 640.
Logic: (1st number × 10) + 10 = 2nd number.
33 : 340 ⇒ (33 × 10) + 10 ⇒ 330 + 10 = 340
48 : 490 ⇒ (48 × 10) + 10 ⇒ 480 + 10 = 490
Similarly, 63 : 640 ⇒ (63 × 10) + 10 ⇒ 630 + 10 = 640
