Select the set in which the numbers are related in the same way as are the numbers of the following sets.
(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)
(125, 87, 49), (236, 198, 160)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (277, 239, 201)
Logic : (Second Number x 2) - Third Number = First Number
⇒(125, 87, 49)
(87 x 2) - 49 = 174 - 49 = 125
⇒(236, 198, 160)
(198 x 2 ) - 160 = 396 - 160 = 236
Similarly,
⇒(277, 239, 201)
( 239 x 2) - 201 = 478 - 201 = 277
Hence , (277, 239, 201) is the correct answer.
