Money!Algebra Level 3
A person wants to withdraw \(X\) rupees and \(Y\) paise from the bank. But the cashier made a mistake and gave him \(Y\) rupees and \(X\) paise. Neither the person nor the cashier noticed that. After spending 20 paise, the person counts the money. And to his surprise, he has double the amount he wanted to withdraw. Find \(X + Y\).
