Question

Anu's father is thrice as old as Anu. After 15 years, his age will be twice that of his daughter. find their present ages​

Answer 1

Step-by-step explanation:

let Anu's age be x

so his father's age be 3x

AFTER 15 YEARS

Anu's age will be x +15

father's age will be 3x +15

hence, equation so formed is :-

3x+15 = 2(x +15)

3x + 15 = 2x + 30

3x - 2x = 30 - 15

x = 15

so Anu's age = 15

her father's age = 3x

= 3 × 15

= 45
