Data Interpretation and Caselets — Practice

Question 1

A table shows sales of three products — A: 200, B: 300, C: 500. What is the total sales figure?
(a) 1000 (b) 900 (c) 800 (d) 1100

Accepted Answer

(a) 1000.

Total = 200 + 300 + 500 = 1000. Reading and summing the column is the first move in most table questions.

Question 2

From the same table (A: 200, B: 300, C: 500), what percentage of total sales does product C account for?
(a) 50% (b) 40% (c) 25% (d) 30%

Accepted Answer

(a) 50%.

Share of C = (500 / 1000) × 100 = 50%, using percentage share = category value ÷ total × 100.

Question 3

In a pie chart, a category makes up 25% of the total. What is the angle of its sector?
(a) 90° (b) 25° (c) 72° (d) 120°

Accepted Answer

(a) 90°.

Angle = (percentage/100) × 360° = (25/100) × 360° = 90°. The whole pie is 360° = 100%.

Question 4

A sector of a pie chart has an angle of 72°. What percentage of the total does it represent?
(a) 20% (b) 25% (c) 18% (d) 30%

Accepted Answer

(a) 20%.

Percentage = (angle/360°) × 100 = (72/360) × 100 = 20%.

Question 5

A company's revenue rose from ₹40 lakh in 2023 to ₹50 lakh in 2024. What is the percentage growth?
(a) 25% (b) 20% (c) 10% (d) 12.5%

Accepted Answer

(a) 25%.

Change% = (50 − 40) / 40 × 100 = (10/40) × 100 = 25%, taken on the earlier value ₹40 lakh.

Question 6

A school has 200 students, of whom 80 are girls. What percentage of the students are girls?
(a) 40% (b) 45% (c) 35% (d) 50%

Accepted Answer

(a) 40%.

Percentage of girls = (80 / 200) × 100 = 40%.

Question 7

A monthly budget of ₹30,000 is split as Rent 40% and Food 30%. By how much does the Rent amount exceed the Food amount?
(a) ₹3,000 (b) ₹2,000 (c) ₹4,500 (d) ₹1,500

Accepted Answer

(a) ₹3,000.

Rent = 0.40 × 30,000 = ₹12,000; Food = 0.30 × 30,000 = ₹9,000. Difference = 12,000 − 9,000 = ₹3,000. The 10-point gap in shares is 10% of ₹30,000.

Question 8

Over five days a shop sold 20, 25, 30, 15 and 10 units. On which day did sales equal 25% of the five-day total?
(a) Day 2 (b) Day 1 (c) Day 3 (d) Day 4

Accepted Answer

(a) Day 2.

Total = 20 + 25 + 30 + 15 + 10 = 100 units. 25% of 100 = 25 units, which is Day 2's figure. Rebuilding the prose into a table makes the read direct.
