Step by step solution :

1.

ans)11:5

Present age of father to the present age of son = 55:25

= 55:25=55/25

simplest form = HCF of 55 ans 25=5

55÷5/25÷5=

11:5

ans)11:5

2.

ans)4:1

Age of father to the age of Son when son was 15 years old.

=40:10

=40:10=40/10

simplest form =HCF of 40 and 10=10

40÷10/10÷10=

4:1

ans)4:1

3.

ans) 13:7

Age of father after 10 years to the age of son after 10 years .

=65:35

65:35=65/35

simplest form =HCF of 65 and 35=5

65÷5/35÷5=

13:7

ans)13:7

4.

ans)2:1

Age of father to the age of son when father will be 60 years old.

=60:30

60:30=60/30

simplest form =HCF of 60 and 30 =30

60÷30/30÷30=

2:1

ans)2:1
