Answer 1

Step-by-step explanation:

If in a proportion, the first, second and fourth terms are 32,112 and 217 respectively, find the third term.

Answer

Correct option is

A

62.

We know that,

four numbers are said to be in proportion if the product of means = product of extremes.

Let the third proportion be x.

=> 32:112::x:217

=> 32×217=112×x

=> x=62
