Solved Examples of AGES
Example 1
So man’s age is 48 years
Example 2: Difference of ages of A and B is 16 years. Four years ago the ratio of ages of A and B was 11 : 7. What is the present age of B.
Solution: Let the age of B be x
So A’s age was x + 16 – 4 = X + 12
Four years ago B’s age was X – 4
As per the statement four years ago the age of A:
Age of B was 11:7
So formulating the equation
Cross multiply 7 X + 84 = 11 X – 44
or 128 = 4x
or X = 32 So B’s present age is 32 yrs.
