Question
The sum of present ages of 2 persons A and B is 60.
If the age of A is twice that of B, Find the sum of their ages 5 years hence.
A 50
B 60
C 70
D 80
Solution
Let's solve this step by step:
Step 1: Let's assume the present age of person B is x.
Step 2: Given that the age of person A is twice that of B, the age of person A will be 2x.
Step 3: According to the problem, the sum of their present ages is 60. So, we can write the equation as x + 2x = 60.
Step 4: Solving this equation, we get 3x = 60. Therefore, x = 60/3 = 20. So, the present age of person B is 20 years and the present age of person A is 40 years.
Step 5: Five years hence, the age of person B will be 20 + 5 = 25 years and the age of person A will be 40 + 5 = 45 years.
Step 6: Therefore, the sum of their ages 5 years hence will be 25 + 45 = 70 years.
So, the answer is C70.
