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 /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, 28, 86)
(18, 38, 116)
Answer & explanation
Correct answer: option 1
(13, 28, 86)
(18, 38, 116)
The logic followed here is :
(IIIrd number - second number ) = ( Ist number × 4) + 6
As
(86 - 28) = ( 13 × 4) + 6
58 = 58
(116 - 38) = ( 18 × 4) + 6
78 = 78
same as in (10, 22, 68)
(68 - 22) = ( 10 × 4) + 6
46 = 46
