Find the least number of oranges needed to satisfy the thirst of 23 football players if one glass of juice requires 5 oranges and each player drinks 2 glasses of juice.

 
762

230
267

276 cannot be the answer because 230 (230/6) approximately gives 267 and not 276.

The answer should be 45 because 45 reversed gives 54 which is 9 more than the original number. The suggested answer is incorrect.
