A vendor paid $175 for a basket of mangoes. He bought 10% of the mangoes and sold the remainder at $2.50 each for a profit of $5o. How many mangoes did he purchase?
-----------------
He paid $175 for x mangoes.
Each mango cost him $(175/x)
------
He sold 0.9x of the mangoes at $2.50 each.
He received 2.5(0.9x) = $2.25x
---
Equation:
Selling price - Buying price = $50
2.25x - 175 = 50
2.25x = 225
x = 100 (original # of mangoes)
