A Sunday (14th April 2024) mathematical fun puzzle!
For many people Sunday is the day to relax and enjoy. The whole day is available for various leisurely activities that we were planning and waiting for Sunday throughout the week.Many of us might like to amuse and entertain ourselves by getting engaged with some fun activity like playing an indoor game or solving a puzzle or riddle, etc.
Today is Sunday (14th April 2024) and I am presenting a puzzling situation which might provide some fun and opportunity to analyse it from puzzle solving attitude.
I solicit the responses, comments, and observations of the members on this mathematical fun puzzle.
Puzzle:
Three friends went to a hotel for taking some snacks, tea/coffee, etc and after having that got a bill for Rs 300. They splitted it and each paid Rs 100. As they left the hotel and started walking outside, the counter person realised that he had by mistake charged Rs 300 in place of Rs 270. So, he called the waiter and gave him Rs 30 to return it to them. The waiter had good change in his pocket and he quickly caught them outside and instead of returning Rs 30 returned only Rs 24 to them and cleverly kept Rs 6 in his pocket. They thanked him and proceeded ahead and distributed Rs 8 to each among themselves.
Initially everyone paid Rs 100 but after getting Rs 8 back their individual expenditure became only Rs 92. It means they spent a total of 3 x 92 = Rs 276 only.
So, they spent Rs 276 and waiter kept Rs 6 with him and that makes a total of 276 + 6 = Rs 282 only. But we started with Rs 300 and our calculations are bringing us to a total of Rs 282 only. It looks there is a mismatch of 300 - 282 = Rs 18.
Why this mismatch? Is't it puzzling?
