4.) Today, the age of a father is thrice the age of his son. After 5 years the
age of father will be 2.5 times the age of his son. What is the age of son
today?​

Answer 1

son age is 15year and father age is 45 year

Step-by-step explanation:

let the son age be x than father age be 3x

after 5 year son age be x+5

and after 5 year father age be 3x+5

2.5 (x+5)=3x+5

2.5x+12.5=3x+5

12.5-5=3x-2.5x

7.5=0.5x

x=7.5×10by0.5×10

x=75by5

x=15

son age is 15 and father age be 15×3=45
