Answers
Given -
- A man is five times old as his son. After 14 years he will be only thrice as old as his son.
To find -
- Their present ages.
Solution -
Let the common ratio be termed as x
Son's age = x
man's age = 5x
After 14 yrs -
Son's age = x + 14
Man's age = 5x + 14
So,
now, we will make a linear equation, and then we will equate the whole expression.
On substituting the values -
5x + 14 = 3(x + 14)
5x + 14 = 3x + 42
5x - 3x = 42 - 14
2x = 28
x =
x = 14
Now -
Son's age = 14yrs
Man's age = 5 × 14 = 70yrs
The present ages of man and son is 14yrs and 70yrs
