Question No 23

In three coloured boxes - Red, Green and Blue, 108 balls are placed. There are twice as many balls in the green and red boxes combined as there are in the blue box and twice as many in the blue box as there are in the red box. How many balls are there in the green box ?

Select the correct answer


Solution!
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.
