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).
(17, 24, 58)
(26, 37, 89)
Answer & explanation
Correct answer: option 1
(17, 24, 58)
(26, 37, 89)
The logic followed here is :
(IIIrd number - second number) ÷ 2 = Ist number
same as
(58 - 24) ÷ 2 = 17
(37- 26) ÷ 2 = 26
Therefore (15, 17, 47)
(47- 27) ÷ 2 = 15
