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)
(23, 308, 15)
(18, 187, 12)
Answer & explanation
Correct answer: option 1
(23, 308, 15)
(18, 187, 12)
The logic followed here is :
(Ist number × IIIrd number) - ( Ist number + IIIrd number) + 1 = second number
As
(23 × 15) - ( 23 +15 ) + 1 = 308
(18 × 12) - ( 18 +12 ) + 1 = 187
same as in (14, 104, 9)
(14 × 9) - ( 14 +9 ) + 1 = 104
