A factory has completed an output value of 2.4 million yuan, which is less than the original plan (1/4). If it wants to exceed production (1/5), how many yuan will it have to complete the output value?
某厂已完成产值240万元，比原计划少(1/4)，如果要超产(1/5)，还要完成产值多少万元？
<gadget id="calculator">1 / 4</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">1 - (1/4)</gadget>
<output>3/4 = around 0.75</output>

<gadget id="calculator">240 / (3/4)</gadget>
<output>320</output>

<gadget id="calculator">1 / 5</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">1 + (1/5)</gadget>
<output>6/5 = around 1.2</output>

<gadget id="calculator">320 * (6/5)</gadget>
<output>384</output>

<gadget id="calculator">384 - 240</gadget>
<output>144</output>

<result>144</result>
