Introduction:
In this problem, we are given that the difference between the ages of two people is 8 years. We are also given that 12 years ago, the elder person was twice the age of the younger person. We need to find the ratio of their present ages.
Let's assume:
Let the present age of the younger person be x years.
Then, the present age of the elder person will be (x + 8) years.
Age 12 years ago:
12 years ago, the age of the younger person would be (x - 12) years.
And the age of the elder person would be (x + 8 - 12) years = (x - 4) years.
Given Information:
According to the given information, 12 years ago the elder person was twice the age of the younger person.
So, we can write the equation: (x - 4) = 2(x - 12).
Solving the equation:
Let's solve the equation to find the value of x.
x - 4 = 2x - 24 (Using distributive property)
x - 2x = -24 + 4 (Transposing terms)
-x = -20
x = 20
Calculating present ages:
The present age of the younger person is x = 20 years.
The present age of the elder person is x + 8 = 20 + 8 = 28 years.
Ratio of their present ages:
To find the ratio of their present ages, we divide their ages by their common factor, which is 4.
Ratio of their present ages = 20/4 : 28/4 = 5 : 7
Conclusion:
Therefore, the ratio of their present ages is 5 : 7, which corresponds to option 'C'.
