Answer 1

Answer:

• The present age of Yasmeen's = 10 years
• The present age of Yasmeen's mother = 40 years

Given:

• Yasmeen's mother is four times as old as Yasmeen. After 5 years, her mother will be three times as old as her.

Need to find:

• The present age of Yasmeen's = ?
• The present age of Yasmeen's mother = ?

Solution:

• Let the age Of Yasmeen = y
• Then, the age Of Yasmeen's Mother = 4y

5 years ago:

• The age of Yasmeen = y + 5
• The age of Yasmeen's Mother = 4y + 5

According To The Question:

4y + 5 = 3 × (y + 5)

➜ 4y + 5 = 3y + 15

➜ 4y - 3y = 15 - 5

➜ y = 10

Therefore:

• The present age of Yasmeen is 10 Years.
• Present age of Yasmeen's mother = 10 × 4
• Present age of Yasmeen's mother = 40 Yrs

Answer 2

Step-by-step explanation:

Let Yasmeen's age be 'x'

her mothers age = 4x

after 5 yrs,

Yasmeen's age =3( x+5)

her mother's age = 4x+5

therefore their present ages

=4x+5 = 3(x+5)

4x+5=3x+15

=x=10

Yasmeen's age =10

mothers age= 40
