Gatik and Manul each have a collection of tennis balls. Gatik said that if Manul would give him 8 of his balls they would have an equal number; but, if Gatik would give Manul 8 of his balls, Manul would have 3 times as many balls as Gatik. How many balls does Manul have?

Lets assume Manul has X and Gatik has Y

Now we can make two equations

X-8 = Y+8 or X-Y = 16 X+8 = 3(Y-8) or 3Y-X = 32 on solving these two we will get X=40 & Y=24
