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)
(51, 34, 85)
(67, 42, 109)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (73, 38, 111)
Logic: The sum of first two digits is equal to the third digit
(51, 34, 85) = 51 + 34 = 85
(67, 42, 109) = 67 + 42 = 109
Similarly,
(69, 44, 102) = 69 + 44 = 113 not 102
(56, 31, 77) = 56 + 31 = 87 not 77
(78, 51, 119) = 78 + 51 = 129 not 119
(73, 38, 111) =73 + 38 = 111
Hence, (73, 38, 111) is the correct answer.
