Mr. Suresh went into a restaurant and had a lunch worth Rs. 162. He paid using a 500 rupee note. Happy with the meal, he then bought a mini snack box for Rs. 37 and paid using a 100 rupee note. In both cases, Suresh collected his balance change from the cashier, and he did not pay any tips. The next day, when the cashier deposited the money in the bank, the banker found that only the two currency notes given by Suresh were counterfeit. As per policy, the bank tore up both notes on the spot. What is the total loss to the restaurant in this transaction?
