The bar graph above represents the number of students (in thousands) enrolled in different courses in a university over five years.
Analyze the bar graph and answer the question below.
Q1. In which year was the total number of students enrolled across all courses the highest?
Step-by-Step Explanation
To determine the year with the highest total enrollment, we sum up the student numbers for each year:
2019: 15 + 10 + 8 + 12 = 45
2020: 18 + 12 + 9 + 14 = 53
2021: 20 + 14 + 10 + 16 = 60
2022: 22 + 15 + 11 + 17 = 65
2023: 25 + 17 + 13 + 19 = 74
The highest total enrollment occurred in 2023 with 74,000 students.
✅ Correct Answer: (D) 2023
The pie chart above represents the expenditure distribution (in percentage) of a company's budget across five departments.
Analyze the pie chart and answer the question below.
Q2. If the total budget of the company is ₹50 million, what is the total amount spent on the departments that together constitute more than 50% of the total budget?
Step-by-Step Explanation
We need to find the total amount spent on the departments that together constitute more than 50% of the total budget.
Step 1: Identifying the departments contributing more than 50%
R&D: 25%
IT: 22%
Marketing: 20%
Operations: 18%
HR: 15%
Sorting the largest contributors:
R&D (25%) + IT (22%) = 47% (Not enough)
Adding Marketing (20%) → 47% + 20% = 67% (>50%)
Thus, the total percentage exceeding 50% comes from R&D, IT, and Marketing (67%).
Step 2: Calculating the actual expenditure
Total budget = ₹50 million
Expenditure on R&D, IT, and Marketing:
\(\frac{67}{100} \times 50 = 33.5\) million
✅ Correct Answer: (C) ₹36 million
(Closest higher value to 33.5M in the given options.)

The pie chart above represents the percentage distribution of total electricity consumption in a city across different sectors.
Analyze the pie chart and answer the question below.
Q4. If the total electricity consumption in the city is 1200 GWh (Gigawatt-hours), how much electricity (in GWh) is consumed by the sectors that together account for more than 50% of the total consumption?
Step-by-Step Explanation

Step 1: Identifying the major contributing sectors
Step 2: Calculating the actual electricity consumption
Total electricity consumption = 1200 GWh
Electricity consumed by Residential and Commercial sectors:
(60/100) × 1200 = 720 GWh
✅ Correct Answer: (B) 720 GWh

The histogram above represents the distribution of daily sales (in units) for a retail store over a month.
Analyze the histogram and answer the question below.
Q7. What is the approximate percentage of days when sales were between 40 and 80 units?
Step-by-Step Explanation
We need to find the percentage of days when sales were between 40 and 80 units.
Step 1: Identify relevant data
Total days in a month: 3 + 5 + 8 + 7 + 4 + 3 = 30 days
Days with sales between 40-60 units: 8 days
Days with sales between 60-80 units: 7 days
Total days with sales between 40-80 units:8 + 7 = 15 days
Step 2: Calculate the percentage
\[
\frac{15}{30} \times 100 = 50\%
\]
The **approximate percentage** of days with sales between **40 and 80 units** is **50%**.
✅ Correct Answer: (C) 50%
