Question

5. After 10 years Karim will be three times as old as today. Find his present age.
​

Answer 1

Answer:

Let the age of Kareem and his son be x and y respectively

According to question ,

x=3y⟶(i)

After 10 years,

Age of Kareem =x+10

Age of his son =y+10

∴(x+10)+(y+10)=76

x+y=56⟶(ii)

x−3y=0

On subtracting , 4y=56

y=14 years old

putting value of y in ⟶(i)

x=3×14=42 years.
