Select the set in which the numbers are related in the same way as are the numbers of the following set.
(43, 34, 387)
(13, 10, 39)
(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)
Answer & explanation
Correct answer: option 1
The logic followed here:
First number × (First number - Second number) = Third number
(43, 34, 387) → 43 × (43 - 34) = 43 × 9 = 387
(13, 10, 39) → 13 × (13 - 10) = 13 × 3 = 39
Similarly,
(18, 13, 90) → 18 × (18 - 13) = 18 × 5 = 90
Hence , (18, 13, 90) is correct answer
