Answers
Answer:
a] Present age of father=42
Present age of son=14
ratio of age of father to son=42:14
=3: 1
b]Present age of father=42-6=36
age of son when he was 8 year old= 8
ratio=36: 8
=9: 2
c]Age of father after 10 years=42+10=52
Age of son after 10 years=14+10=24
ratio of age of father to son=52: 24
=13: 6
d]age of father =32 years
age of son =14-10=4 years
ratio=32: 4
=8: 1
Given,
The present age of the father is 42 years and that of his son is 14years.
To find
the ratio of-
(a) Present age of father to the present age of the son.
(b) Age of the father to the age of the son, when the son was 8 years old.
(c) Age of father after 10 years to the age of son after 10 years.
(d) Age of father to the age of son when father was 32 years old
Solution,
(a) Ratio of the present age of the father to the present age of the son.
Ratio = 42:14
Ratio = 3:1
(b) Ratio of the age of father to the age of the son, when the son was 8 years old.
Age of father (when the son was 8 years old) = 36 years
Age of the son = 8 years
Ratio = 36 : 8
Ratio = 9 : 2
(c) Ratio of the age of father after 10 years to the age of son after 10 years.
Age of father ( after 10 years to the age of son after 10 years)
Age of father = 48 years ( father was 38 years when the son was 10 years)
Age of the son = 20 years (10 years after son was 10 years old)
Ratio = 48 : 20
Ratio = 12 : 5
(d) Ratio of the age of father to the age of son when father was 32 years old
Age of the father = 32 years
Age of the son = 4 yeas ( 10 years back)
Ratio = 32 : 4
Ratio = 8 : 1
Hence the four ratios are a) 3:1, b) 9:2, c) 12:5, d) 8:1
