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
