Choose the correct option for the missing term.27 : 18 :: 102 : ?

The correct answer is Option (2) → 68

In a number analogy the second pair must stand in the same relation as the first; here the relation is the ratio of the two numbers.

• \(27:18=3:2\) (both divided by 9)

• So \(102:?=3:2\)

• \(\displaystyle ?=102\times\frac{2}{3}=68\)
