Another way to ask the question is:
What is the LEAST number of apples
and pears she can buy and have the
remainder of the money EVENLY
divisible by +15+ pesos/orange
--------------------------------
1 apple & 1 pear:
+25+%2B+20+=+45+
+200+-+45+=+155+
NOT evenly disible by +15+
----------------------------
2 apples & 1 pear:
+2%2A25+%2B+20+=+70+
+200+-+70+=+130+
NOt evenly divisible by +15+
-----------------------------
1 apple & 2 pears:
+25+%2B+2%2A20+=+65+
+200+-+65+=+135+
+135%2F15+=+9+
-------------------
With $135 left after buying 1 apple
& 2 pears, she can buy 9 oranges
which is the most she can buy
