present cages,​

Answer 1

Answer:

son= 10 years, father= 40 years

Step-by-step explanation:

Let the son's age be x

Father's age is 4 times son's age =4x

After 5 years father's age will be 3 times son's age,

I.e. (4x+5)=3(x+5)

As per question we have,

= 4x+5=3(x+5)

= 4x+5=3x+15

=4×-3x=15-5

= x= 10

Therefore, age of son at present is x= 10 years

and the age of father is =4x =4× 10=40 years.
