Answer 2

Answer:

The age of mother is 36 years.

Step-by-step explanation:

Given :

Ratio of ages = 5 : 4

Father's age = 45

To find :

Mother's age

Solution :

Let the ages be -

• Father's as = 5y
• Mother's as = 4y

As father's age is 45, 5y = 45

★ Value of y -

$\sf{\implies} \:y = \dfrac{45}{5} \\ \\ \sf{\implies} \:y = 9$

y = 9

$\rule{300}{1.5}$

★ Value of 4y -

$\sf{\implies} \:4 \times y \\ \\ \sf{\implies} \:4 \times 9 \\ \\ \sf{\implies} \:36$

Mother's age = 36

$\therefore$ The age of mother is 36 years.
