A factory finished a batch of parts in two days. On the first day, it made 15 fewer parts than the total (2/5), and on the second day it made 48 more parts than the remaining 60%. How many parts are there in total?
某工厂两天做完一批零件，第一天做的比总数的(2/5)少15个，第二天做的比余下的60%多48个，零件共多少个？
<gadget id="calculator">60 / 100</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">15 * (3/5)</gadget>
<output>9</output>

<gadget id="calculator">48 - 15</gadget>
<output>33</output>

<gadget id="calculator">9 + 33</gadget>
<output>42</output>

<gadget id="calculator">2 / 5</gadget>
<output>2/5 = around 0.4</output>

<gadget id="calculator">(2/5) * (3/5)</gadget>
<output>6/25 = around 0.24</output>

<gadget id="calculator">(6/25) - (2/5) - (3/5)</gadget>
<output>-19/25 = around -0.76</output>

<gadget id="calculator">1 + (-19/25)</gadget>
<output>6/25 = around 0.24</output>

<gadget id="calculator">42 / (6/25)</gadget>
<output>175</output>

<result>175</result>
