Question

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)
(12,51,5)
(5,36,7)

A.

(14,120,16)

B.

(19,44,3)

C.

(13,10,7)

D.

(11,51,6)

Correct option is D

Logic - three times of first number + three times of third number = second number

(12,51,5) =  36 + 15 = 51
(5,36,7) = 15 + 21 = 36

similarly in option d (11,51,6)

triple of first number 11 =33

triple of third number 6 = 18

second number = 33 + 18 = 51
