Electricity meter card 100 yuan, originally 24 yuan was left. It should be 124 and the result is 60.8 yuan. Who knows what happened?

The electricity meter does not show the balance, but should show the current electricity consumption and available electricity. In this case, you used another electric card to charge a little before inserting your electric card (probably the card of the property electrician). If he charges you ten yuan for electricity, the electricity before you insert the card will be zero, which is also a means for electricians to earn extra money in disguise.
