Select the option in which the numbers are related in the same way as are the numbers of the following set.
(11, 57, 8)
Answer & explanation
Correct answer: option 4
(11, 57, 8)
The logic followed here is :
(Ist number + IIIrd number) × 3 = IInd term
AS we know
11 + 8 = 19
then 19 × 3 = 57
Similarly
(15, 81, 12)
15 + 12 = 27
then 27 × 3 = 81
