Question

Five years ago, Pilar was three times as old as Net, Five years hence Pilar will be twice as old as Net. Find the ages now?

Answer 1

Step-by-step explanation:

Let the age of Pilar be x and Net be y.

According to question:

(x-5)=3(y-5)

x-5=3y-15

x-3y=-15+5=-10-----(1)

(x+5)=2(y+5)

x+5=2y+10

x-2y=10-5=5------(2)

(2)-(1)

x-2y-(x-3y)=5-(-10)

x-2y-x+3y=5+10

y=15.-----(3)

(3) in (2):

x-2(15)=5

x=30+5=35.

Hence, Pilar's age is 35years and Net's age is 15years.
