What Actually Happened:

1. You borrowed 50,000 from each parent:
Total borrowed = 100,000

2. You bought a laptop for 97,000.
You now have 3,000 remaining (100,000 - 97,000)

3. You returned 1,000 to your mother and 1,000 to your father.
Now you owe 49,000 to each parent.
Total debt = 98,000

4. You kept 1,000 with yourself.
Remaining cash with you = 1,000

Now, the trick part:
The mistake is adding the 1,000 you kept to the 98,000 you still owe, like this:

> 49,000 + 49,000 = 98,000
> 98,000 + 1,000 (kept) = 99,000 ← Wrong logic

This is misleading because:
The 98,000 already includes everything you owe, and the 1,000 you kept is part of that 98,000. You’re double-counting the 1,000.

✅ Correct Breakdown:
You owe: 49,000 + 49,000 = 98,000
You have: 1,000 in cash
You spent: 97,000 on the laptop

Total: 97,000 (laptop) + 1,000 (cash) = 98,000 ← exactly what you owe

✅ So, where is the 1,000?
There is no missing 1,000.
The confusion comes from adding the 1,000 to your debt instead of subtracting it from it.

In short:
> You owe 98,000.
> You have a 97,000 laptop + 1,000 cash = 98,000 in value.
> ✅ Everything balances. There is no missing money.
