Let G represent the number of Grandparents.

There were twice as many parents as grandparents:

Let 2G represent the number of Parents

 50 more children than parents.

Let 2G + 50 represent the Children

----------------------------

G + P + C = 400

Solve this equation for G:

G + 2G + 2G + 50 + 400

Post what you get, okay?

directrix · Answer

This above   G + 2G + 2G + 50 + 400   should be G + 2G + 2G + 50 = 400 


G + 2G + 2G + 50 + 400 

5G + 50 = 400

         5*G = 350
