Find the average number of Cello water bottles sold by shop A, D and E.

Percentage of total number of water bottles sold by shop B and C = [100 – (20 + 30 + 25)]% = 25% => 25% ----- 250 => 100% ------ 1000 Total number of water bottles sold by all the shops together = 1000 Number of water bottles sold by shop D = 30% of 1000 = 300 Let number of Milton water bottles sold by shop D be x. Number of Cello water bottles sold by shop D = x/4 According to the question, => x + x/4 = 300 => 5x = 1200 => x = 240 Milton water bottles sold by shop D = 240 Cello water bottles sold by shop D = 240/4 = 60 Similarly, Required average = (40 + 60 + 50)/3 = 150/3 = 50
