- Let R, G and B represent the number of balls in red, green and blue boxes respectively.
Then, .
R + G + B = 108 ...(i),
G + R = 2B ...(ii)
B = 2R ...(iii)
From (ii) and (iii), we have G + R = 2x 2R = 4R or G = 3R.
Putting G = 3R and B = 2R in (i), we get:
R + 3R + 2R = 108 6R = 108 R = 18.
Therefore Number of balls in green box = G = 3R = (3 x 18) = 54. - 11 years agoHelpfull: Yes(85) No(8)
- 2(G+R)=B
2B=R
G+R+B=108
G+R+2(G+R)=108
3G+3R=108
B=36ans - 8 years agoHelpfull: Yes(0) No(0)
