Do Not Pay Any Less, Mrs Mess Puzzle
The Puzzle:
 | Mrs Mess was buying a set of garden furniture. The bill was seventy dollars. |
She gave the attendant what she thought were two ₹50 notes, (actually two ₹100 notes).
The attendant was sleepy and didn't notice either, so he gave Mrs Mess what he thought were three ₹10 notes (actually three ₹50 notes).
Who ended up better off than they should?
Mrs Mess comes away better off than she should, by ₹20 in fact. Despite the warning in the title, Mrs Mess did pay less than she should have done!
Cost of furniture: ₹70
Mrs Mess paid: ₹100 x 2 = ₹200
Change received: ₹50 x 3 = ₹150
Net payment: ₹200 - ₹150 = ₹50
Profit for Mrs Mess: ₹70 - ₹50 = ₹20
