Question

If in a proportion, the first, second and fourth term are 32, 112 and 217
respectively, then the third term is

• A. 45
• B. 32
• C. 62
• D. 78

Answer 1

The correct option is C 62

Let the third term be x
Therefore, 32 : 112 :: x : 217
so, $\frac{32}{112}=\frac{x}{217}$
$x=\frac{32\times 217}{112}$
$x=62$
So, the third term is 62.
