A small table of runs, marks or books read can answer many questions: the total, the difference between the highest and the lowest, who has the most, or how many are above a mark.
Read, then compare — “find the values the question needs, then add, subtract or compare”
Read the table and underline the values the question needs.
Total: add all. Difference: bigger − smaller. Most/fewest: compare every value.
“More than 30” does not include 30 itself — check each value.
Use it for: Data interpretation in Olympiads, aptitude tests and Class 6–10 maths (tables and bar graphs).
Worked example: Runs scored in a cricket match: Aarav 34, Diya 28, Kabir 45, Meera 19, Rohan 31. What is the difference between the highest and the lowest? → 26
Work it out in your head or on paper, then tap your answer — or type it and press Check. Stuck? Press “Show me how”.
