If total number of Milton water bottles sold by shop B is 20% of the number of total water bottles sold by shop (B+

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, Number of Milton water bottles sold by shop B = (20/100) × 250 = 50 Required difference = 50 – 40 = 10
