Two numbers are in the ratio 5 : 6. If 8 is subtracted from each of the numbers, the ratio becomes 4 : 5, find the numbers.
The question is based on the concepts of linear equations in two variables and ratios.
Answer: The two numbers are 40 and 48, which are in the ratio 5 : 6.
Let's find the numbers.
Explanation:
Let the numbers be 5x and 6x.
Given that, if 8 is subtracted from each of the numbers, the ratio becomes 4 : 5.
(5x - 8) : (6x - 8) = 4 : 5
(5x - 8) / (6x - 8) = 4 / 5
5(5x - 8) = 4(6x - 8)
25x - 40 = 24x - 32
25x - 24x = 40 - 32
x = 8
the first number = 5x = 5 × (8) = 40
the second number = 6x = 6 × (8) = 48
Thus, the numbers are 40 and 48 which are in the ratio 5 : 6.
