Lesson 7 of 7 · Combination charts

Max min

DI: Mixed / Combination · for IPMAT Indore, IPMAT Rohtak and JIPMAT

The idea of Combination charts

A mixed (combo) DI set gives two linked displays: a pie with a bar, a bar with a ratio table, a pie with a line. One display gives shares or totals, the other splits them further. The key step is the cross-reference: carry a number from one display into the other.

The exam method

  1. Fix the base once. the clue that is a single number (prose gap 27, revenue 15180, total 90000) usually fixes every count.
  2. Build one row per category. only for the categories asked.
  3. Let totals cancel. in ratio questions.
