(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits.)
(2, 4, 18)
(1, 9, 50)
Answer & explanation
Correct answer: option 1
(2, 4, 18)
(1, 9, 50)
The logic followed here is :
(Ist number + second number ) × (Ist number + second number ) ÷ 2 = Third number
As
(2 + 4) × (2 + 4) ÷ 2 = 18
(1 + 9) × (1 + 9) ÷ 2 = 50
Similarly in option 1
(3 + 5) × (3 + 5) ÷ 2 = 32
