Problema Solution
the sum of patricia, jane and paul is 100. jane is twice as old as patricia. john is 5 years older than jane. how old is each one of them
Answer provided by our tutors
Let
x = the age of Patricia
y = the age of Jane
z = the age of John
x + y + z = 100
y = 2*x
z = y + 5
By solving the equation we find
x = 19 years
y = 38 years
z = 43 years
Patricia is 19 years old, Jane is 38 years old John is 43 years old.
