The ratio of total number of red balls sold to the total number of orange balls sold is :
Solution
Since all the shops sell the same number of balls, total number can be equated to total percentage (Since ratio is asked)
Total number of redballs sold = 0 + 35+0+ 20+ 45 = 100
Total number of orange balls sold = 30 + 30+ 35 + 50 = 145
Ratio = 100:145 = 20:29
