Answer 1

Answer:

Ashu present age is 5 years

and her mother age is 125 years.

Answer 2

Answer:

Ashu's age → 5 years ; Mother's age → 25 years

Step-by-step explanation:

According to the question,

⇒ ( x² + 5 ) = 3( x + 5 )

⇒ ( x² + 5 ) = 3x + 15

⇒ x² - 3x + 5 - 15 = 0

⇒ x² - 3x - 10

By splitting the middle term,

⇒ x² - 3x - 10

⇒ x² + 2x - 5x - 10

⇒ x( x + 2 ) - 5( x + 2 )

Therefore,

x = -2 and x = 5

Since, age cannot be negative, Ashu's age will be 5 years

Therefore,

mother's age = x² = 5² = 25 years
