Select the set in which the numbers are related in the same way as 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)
(82, 35, 78)
(18, 27, 30)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (27, 33, 40)
The logic is used here:
Third number = (First number + Second number) ÷ 1.5
(82, 35, 78) = (82 + 35) ÷ 1.5 = 117 ÷ 1.5 = 78
(18, 27, 30) = (18 + 27) ÷ 1.5 = 45 ÷ 1.5 = 30
Similarly,
(27, 33, 40) = (27 + 33) ÷ 1.5 = 60 ÷ 1.5 = 40
