@Python_Dv White ball weighs 25....
Solution...
Let Red ball = X
Let White ball = Y
Solving the left side ..
3X = 30
X = 10.
Solving for white ball ..
2Y + X = 30 + 3X
2Y = 30 + 2X
Y = 15 + X
Y = 15 + 10
Y = 25
@Python_Dv I think 25 is the answer ,Because 3 red balls are equal to 30 so one red will 10 and other side two white balls and one red. 30 + 30=60 = for other side where two balls { 10+30+30 }
@Python_Dv Well there are manu solutions if you think about it, White might be 15 and red 0.
White might be 45 and red 30.
White might be 25 and red 10
