We have a 'n' sided polygon. The number of diagonals that pass through its centre is?
Five hundred rupees were divided among three friends - Atul, Bharat and Chirag. The amount received by each of them is a distinct three-digit natural number. The maximum amount, out of these three amounts, is a perfect square and has the same digit twice. When asked about the amount, they received, each of them made 2 statements. They belong to either of the two categories- Truth teller or an Alternator. A truth teller always tells the truth and an alternator makes a true statement followed by a wrong statement or vice versa. Following were their replies -
Atul - "I have the highest amount".
- "Amount with me is more than the sum of the amounts received by the other two persons".
Bharat - "Amount with me is a perfect square".
- "I have the highest amount".
Chirag - "I did not get the lowest amount".
