Homework Statement
Pritesh is taller than Davina who is taller than Alicia. The difference in height between Pritesh and Davina is the same as the difference in height between Davina and Alicia. The total of their heights is 300 cm. How tall is Davina?
Homework Equations
Now trial and error gives me Alicia = 50cm, Davina = 100cm and Pritesh = 150cm as the difference between them is 50cm
The Attempt at a Solution
How could I do this problem using only algebra, rather than what I did with trial and error?
