The following table shows the number of bottles of 6 different colours sold by a shop in a month.

The total number of bottles of C4 and CS sold in that month is approximately what percentage of the total number of bottles of all the 6 colours taken together sold in that month?

29.17%

Total number of sold bottles of C4 and C5 = 42 + 28 = 70

Total number of bottles in all 6 colors = 46 + 34 + 50 + 42 + 28 + 40 = 240

Required percentage = \(\frac{70 }{240}\) × 100

= 29.17%
