Banana bought 3 companies for
A :$20000000
B : $250000000
G : $350000000
He made a profit of $(9.6x10^6) when he sold the companies. He also made a profit of 25% on A and loss of 10% on B. Find the percentage profit he made on G.
How do I do this? What are the fixed steps? Thanks so much! :)))))

Let a,b,g be the cost of the companies
To make things simpler, let's deal in millions (10^6)
1.25a = 20
.9b = 250
a = 16
b = 277.77777
profit on a = 4
profit on b = 27.77777
profit on g = 9.6 (427.777) = 33.3777
g = 35033.3777 = 316.62222
%profit on g is profit/cost = .105 = 10.5%
