We have attendance of three days in the ratio 1 : 2: 5 Let us take m people visited on day 1, 2m people visited in day 2, and 5m people visited on day 3. Hence total people visited = m + 2m + 5m = 8m Total amount of money spent by m people who visited on day 1 = 14 × m = 14m Total amount of money spent by 2m people who visited on day 2 = 12 × 2m = 24m Total amount of money spent by 5m people who visited on day 3 = 10 × 5m = 50m Total money spent by 8m people = 14m + 24m + 50m = 88m Average money spent by each person = Total money spent/total persons visited = 88m/8m = Rs 11Related questions
