Answer 1

A Mother is three times as old as her daughter. 5 year later,the mother will be two and a half times as old as her daughter find the age of the daughter and that of mother in year. So, Daughter's age = 15 years. ⇒ 3 × 15 = 45 years.

Answer 2

Answer:

mothers age is 30 and daughter age is 10

Step-by-step explanation:

let the present age of the mother be x and that of daughter be y

• given=
• x=3×y
• x-3y=0__equ 1
• x-5=5⁽y-5₎
• x-5=5y-25
• x-5y=-25+5
• x-5y=-20__equ 2
• subtract equ 1 - 2
• we get
• -2y=-20
• y=10
• substitute y=10 in equ 1
• x-3(10)=0
• x-30=0
• x =30
