Question 731055: five years ago, the director was 3 times older than one of the youngest student, now their combined ages amount to 110 years thus, the present age of the director is?
You can put this solution on YOUR website! student's age =x
5 years ago
student's age x-5
director's age =3(x-5)
now student's age =x
director's age = 3(x-5)-5
x+3(x-5)+5=110
x+3x-15+5=110
4x-10=110
4x=120
x=30 student's age now
plug x to get director's age
