研究方向

開啟 shared/practice/questions.json,先閱讀現有的定量問題,以符合其結構。新增三個原創的連續百分比變化問題,每個問題包含四個選項、一個有效的答案 ID,以及展示計算過程的解釋;保持現有 ID 不變。執行 npm ci 和 npm test 來檢查題庫。

描述

enhancement good first issue

What to add

Add 3 original multiple-choice questions on successive percentage changes to the quantitative topic in shared/practice/questions.json.

The quantitative topic has 6 questions and none of them cover successive percentage changes yet. Some ideas (write your own wording and numbers):

  • an increase followed by a decrease of the same percentage
  • two discounts applied one after the other
  • a value that grows by a fixed percentage for two years

Look at the existing quantitative questions in the file first and follow the same shape.

Requirements

  • The questions must be your own. Do not copy from books, websites, coaching material, or past papers.
  • Each question has exactly 4 options (a to d), one answerId, and an explanation that shows the reasoning or working, not only the answer.
  • Use "topicId": "quantitative" and "difficulty": "easy" or "medium". A mix of both is welcome.
  • Give each question a new lowercase ID, for example quant-successive-discount. Do not change existing IDs.
  • Indian context is welcome (Rs, km, common names).

Check your change

npm ci
npm test

npm test checks the question bank (unique IDs, four distinct options, a valid answer). If you have the .NET SDK, also run dotnet test backend/ProCoderJi.slnx --configuration Release. If you don't, CI runs the backend tests on your pull request.
