A fruit seller sold 25% of his oranges on Monday, 20% of the remainder on Tuesday. He had 156 oranges left. How many oranges did he had at first? How many oranges did he sell altogether?
----
Starting # of oranges:: x
After selling 25%:: 0.75x
After selling 20%:: 0.80*0.75x
-----
Equation:
0.8*0.75x = 156
x = 260 (# he started with)
260-156 = 104 (# he sold)
