What is the approximate average number of chocolates purchased by Sumit from shop A, B and D together?
Number of chocolates purchased by Sumit from shop A = [(30/100)×200] – 45 = 60 – 45 = 15 Number of chocolates purchased by Sumit from shop B = [(25/100)×200] – 30 = 50 – 30 = 20 Number of chocolates purchased by Sumit from shop D = [(20/100)×200] – 10 = 40 – 10 = 30 Required average = (15 + 20 + 30)/3 = 21.66≈22
