Question

4. A man is 3 times as old as his son. After 15 years, he will be only twice as old as his son. Find the
present ages.​

Answer 1

Answer:

45 and 15

Step-by-step explanation:

Let man age=x  

Son age= y

x=3y..........Eqn 1

x+15 = 2(y+15)

x+15 = 2y + 30

3y +15 = 2y + 30          (Substituting x=3y in this equation)

y= 30=15

y=15

Thus, x=45
