Answer 2

Given:

Riya's present age is x years.

To Find:

Write an expression for each of the  following:

i) Her brother is 2 years younger.

ii) Her father's age exceeds her age by 35 years.

ii) Her mother's age is three years less than that of her father.

Solution:

It is given that the age of Riya is x years and we need to find,

(i) If her brother is 2 years younger, that means the age of her bother will be 2 less than the age of his sister, so

$Brother=x-2$

Hence, the expression for her brother's age is (x-2).

(ii) If her father age exceeds her age by 35 years, that means that the age of her father is 35 years more than her age, so

$Father=x+35$

Hence, the expression for her father's age is (x+35).

(iii) If the age of her mother is 3 years less than that of her father then,

$Mother=(x+35)-3\\=x+32$

Hence, the expression of her mother's age is (x+32).
