In the given number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the number-pair in which the numbers are related in the same way as are the numbers of the given number-pairs. (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/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.)
(19, 200)
(15, 160)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (22, 230)
⇒ (19, 200)
19 × 10 = 190 + 10 = 200
⇒ (15, 160)
15 ×10 = 150 + 10 = 160
Similarly,
⇒ (22, 230)
22 × 10 = 220 + 10 = 230
