if a:b :: c:d
then, (a*d) = (b*c) [Property of Ratio n proportion]
So,
if, 123 : 36 : : 221 : x
Then, 123*x = 36*221
i.e, x = 65
(It may be the dummy question as none option is having right answer)

let X
123*X=36*221
X=65

by the property of ratio n proportion product of extremes are equal to product of means
i.e a*d=b*c
123*x=36*221
x=64.68
~=65
