(b) Age of the father to the age of son, when son was 12 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 30 years old.

Answer 1

HEYA MATE, HERE IS UR ANSWER __________________________

a)Ratio of father's age to the son = 42:14
=3:1

b) When son was 12 years old , father's age = 42-2
=40 years.
Ratio of Father's age to the son's age when son was 12 years old=40:12
=10:3

c)Age of father after 10 years =42+10
=52 years
Age of son after 10 years =14+10
=24years
Ratio of father's age to son's age after 10 years = 52:24
=13:6

d)When was 30 years old 42-30 = 12 years back.
son's age 12 years back =14-12

Answer 2

$\huge \blue{HELLO}$

$\large \mathfrak{ANSWER : }$

Ans: (a) Given, present age of father = 4²

gas

Present we of seen = 14 Years

The ratio of present age of father the present age of son

$= 42 : 14$

$= \frac{42 \div 2}{14 : \div 2} : \frac{21 \div 7}{7 \div 7}$

$\frac{21 \div 7}{7 \div 7} = \frac{3}{1}$

= 3 : 1

Ans: (b) Son's we when he 13 years 14 - 12 = 2³ years before.

Father's age before 2 year = 4² - 2

. = 40 years

The ratio of the father's age to son's age when soon years 12 years old

$= 40 :12$

$= 40 \div 2$

$12 :2$

$10 : 3$

$20 \div 2$

$6 \div 2$

$= 1 : 3$

Ans: (c) Age of father after 10 years

= 42+10

=52 years

Age of son after 10 years

= 14+10

=24 years

The ratio of father age to son's age after 10 years

$= 52 :4$

$= \frac{52 \div 4}{24 \div 2} = \frac{26 \div 2}{12 \div 2} = \frac{13}{6}$

$= 13 : 6$

Ans: (d) Father age was 30 years

= 42-30

= 12 year before

son age was = 14 - 12

= 2 years

The ratio of the father is 2 years
