Paid subscribers 1200, 1800, 3000, 4500, 6000; unpaid 2400, 1500, 2350, 4200, 2520. What is the ratio of the averages?

Solution: 1650 : 1297. Totals 16500 : 12970.

A city has 36 lakh people and 47% are females. How many males?

What are the common traps in Simple / grouped bar questions?

Wrong base in percent questions (28% vs 21.39% in the subscriber set). Direction word: 16.67% less, not more. Mixed units in one chart: a bar counting people next to bars of percentages.

The idea

A simple or grouped bar chart shows one or several series side by side for each category (months, schools, cities). Questions read one or two bars and do one operation: ratio, average, difference, percent change, share. JIPMAT PYQ bar sets of this kind exist: students appeared vs qualified by city (2025), gross traffic receipts vs expenditure 2015-2019 (2024) and percent growth in GDP by region (2024); they are banked as PYQs in this chapter.

Textbook vs exam method

Textbook method

Read the legend and the axis unit (count, lakh, %, thousand).
Copy the bars you need into a small table.
Do the operation the stem asks for, on the right base.
Match the option, checking the direction word (more/less) and the unit.

Exam method

Derive once. if one series is a percentage of another, write the counts for every category before the questions.
Totals, not averages. compare sums when the divisor is the same.
Cancel early. reduce ratios (480 : 590 = 48 : 59) before multiplying.
Back-solve given ratios. "December : April = 6 : 11" with December = 1800 gives April = 3300 in one step.
