Statement Sums Involving Proportion
Statement Sums involving Proportion:
In the statement we are given a relation and then a value of one thing we are supposed to find the value of the other thing. Sometimes we are given the values of the certain quantities we are supposed to find the whether they are in proportion
Illustration: The first, second and third terms of the proportion are 42, 36, 35. Find the fourth term.
Solution: Let the fourth term be x.
Thus 42, 36, 35, x are in proportion.
Product of extreme terms = 42 ×x
Product of mean terms = 36 X 35
Since, the numbers make up a proportion
Therefore,
product of extreme = product of mean
42 × x = 36 × 35
or,
or, x = 30
Therefore, the fourth term of the proportion is 30.
If first, second and third terms of proportion are first three natural numbers, then the fourth term will be ________________ | |||
