In the family of Mukesh there are 3 members. If 9 years are subtracted from the age of Mukesh and divided by 5 then we get his son Suresh age. If the age of the Mukesh wife is 15/17 times of the Mukesh age and also the age of Suresh friend Sahoo who is 5 years older than him is 10 years old then find the average age of the Mukesh family.
