A factory plans to complete the production task of a batch of parts in one year. The first quarter completed (1/4) of the plan, and the second quarter completed 30% of the plan, which is exactly 400 more than the first quarter. How many parts are planned to be produced in the whole year?
某工厂计划用一年的时间完成一批零件的生产任务．第一季度完成了计划的(1/4)，第二季度完成了计划的30%，正好比第一季度多生产400个，全年计划生产零件多少个？
<gadget id="calculator">30 / 100</gadget>
<output>3/10 = around 0.3</output>

<gadget id="calculator">1 / 4</gadget>
<output>1/4 = around 0.25</output>

<gadget id="calculator">(3/10) - (1/4)</gadget>
<output>1/20 = around 0.05</output>

<gadget id="calculator">400 / (1/20)</gadget>
<output>8_000</output>

<result>8_000</result>
