Answer 1

Answer:

Step-by-step explanation:

let the ages of three persons =7x-10,8x-10,9x-10.

A/q,

⇒7x-10+8x-10+9x-10=150,

⇒24x-30=150,

⇒24x=120,

⇒x=120/24=5,

hence,x=5.

the age of first person =7x-10=35-10=25 age,

the age of second person =8x-10=40-10=30 age,

the age of third person =9x-10=45-10=35 age.
