Select the set in which the numbers are related in the same way as are the numbers of the following set. (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).
(24, 9, 21)
(34, 16, 33)
Answer & explanation
Correct answer: option 4
(24, 9, 21)
(34, 16, 33)
The logic followed here is :
(IIIrd number - Second number ) × 2 = Ist number
As
( 21 - 9 ) × 2 = 24
( 33 - 16) × 2 = 34
Similarly in option
( 30 - 9) × 2 = 42
