I had $5 riddle

Riddle: I had $5. My mom gave me $10 while my dad gave me $30. My aunt and uncle gave me $100. I had another $5. How much money did I really have?

Answer: The correct answer is $10. If you read the question carefully, the question asked about your first money with “how much money DID I really have?”.

The money you had is $10. That is before your parents and relatives gave you additional money. However, given that the logic and time of the tense is in the past, it is safe to assume that the question pertains to the money you had originally before you received external money from someone else.

Therefore, you had $5 and another $5 originally with you, which sums up to $10.
