Riddle: How much did I earn?
I bought a phone for $200.
I sold it for $250.
I bought it again for $300.
I sold it again for $350.
How much did I earn?
Solution:
Let’s break down the transactions step by step:
- First Transaction:
- Bought the phone for $200.
- Sold it for $250.
- Profit from the first transaction = $250 – $200 = $50.
- Second Transaction:
- Bought the phone again for $300.
- Sold it for $350.
- Profit from the second transaction = $350 – $300 = $50.
Total profit from both transactions:
$50 (first profit) + $50 (second profit) = $100.
So, you earned $100.
