Select the option in which the numbers share the same relationship as that shared by the given pair of numbers.
9 : 50
Answer & explanation
Correct answer: option 4
9 : 50
The logic followed here is :
(Ist term +1)2 ÷ 2= IIIrd term
As
(9 + 1)2÷ 2 = 102 ÷ 2
and 100 ÷ 2 = 50
Same as
13 : 98
(13 + 1)2÷ 2 = 142 ÷ 2
and 196 ÷ 2 = 98
