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)
(15, 9, 4)
(7, 2, 3)
Answer & explanation
Correct answer: option 2
(15, 9, 4)
(7, 2, 3)
The logic followed here is :
(Ist term - second term) = X then ( X - 2 )= third term
15 - 9 = 6 then 6 - 2 = 4
7 - 2 = 5 then 5 - 2 = 3
Similarly in option 2
19 - 13 = 6 then 6 - 2 = 4
