Given:
Two numbers are in the ratio 16:9. The sum of the two numbers is 100.
To Find:
The two numbers are?
Solution:
The given problem can be solved by using simple algebra.
1. The ratio of the two numbers is 16:9.
2. Let the two numbers be 16x and 9x respectively.
3. The sum of the two numbers is equal to 100. Hence, the algebraic equation is,
=> 16x + 9x = 100,
=> 25x = 100,
=> x = 100/25,
=> x = 4.
4. The value of the two numbers are:
=> 16x = 16(4) = 64,
=> 9x = 9(4) = 36.
Therefore, the two numbers are 64 and 36.
