The table shows the number of Type X and Type Y cars sold by a dealership over five days.
| Day | Total Cars Sold | Ratio of X : Y | Type X | Type Y |
|---|---|---|---|---|
| Monday | 120 | 5 : 7 | 50 | 70 |
| Tuesday | 150 | 7 : 8 | 70 | 80 |
| Wednesday | 140 | 5 : 9 | 50 | 90 |
| Thursday | 160 | 3 : 5 | 60 | 100 |
| Friday | 180 | 4 : 5 | 80 | 100 |
Question 1. How many Type Y cars were sold on Tuesday and Wednesday together?
Type Y cars sold on Tuesday = 80
Type Y cars sold on Wednesday = 90
Total = 80 + 90 = 170 cars
Question 2. What is the difference between the number of Type X and Type Y cars sold on Friday?
Type X cars sold on Friday = 80
Type Y cars sold on Friday = 100
Difference = 100 − 80 = 20 cars
Question 3. What is the average number of Type X cars sold from Monday to Friday?
Total Type X cars sold:
50 + 70 + 50 + 60 + 80 = 310
Average = Total ÷ Number of days
Average = 310 ÷ 5 = 62 cars
Question 4. What is the percentage increase in total cars sold on Friday compared with Monday?
Cars sold on Monday = 120
Cars sold on Friday = 180
Increase = 180 − 120 = 60
Percentage increase = (60 / 120) × 100 = 50%
Therefore, the percentage increase is 50%.
Question 5. What is the ratio of Type X cars sold on Tuesday and Friday together to Type Y cars sold on Monday and Thursday together?
Type X cars sold on Tuesday and Friday:
70 + 80 = 150
Type Y cars sold on Monday and Thursday:
70 + 100 = 170
Required ratio = 150 : 170
Divide both numbers by 10:
150 : 170 = 15 : 17
An insurance company received applications for five insurance plans in one month.
| Insurance Plan | Total Applications |
|---|---|
| Plan A | 800 |
| Plan B | 1,000 |
| Plan C | 1,200 |
| Plan D | 1,500 |
| Plan E | 500 |
| Total | 5,000 |
Question 6. What is the total number of applications received for Plans A and C together?
Applications for Plan A = 800
Applications for Plan C = 1,200
Total = 800 + 1,200 = 2,000 applications
Question 7. What percentage of the total applications was received for Plan B?
Applications for Plan B = 1,000
Total applications = 5,000
Percentage = (1000 / 5000) × 100 = 20%
Therefore, the correct answer is 20%.
Question 8. How many more applications were received for Plan D than for Plan E?
Applications for Plan D = 1,500
Applications for Plan E = 500
Difference = 1,500 − 500 = 1,000 applications
Question 9. What is the average number of applications received per plan?
Total applications = 5,000
Number of plans = 5
Average = 5,000 ÷ 5 = 1,000 applications
Question 10. If applications for Plan A increase by 25%, how many applications will Plan A receive after the increase?
Applications for Plan A = 800
Increase = 25% of 800 = (25 / 100) × 800 = 200
New total = 800 + 200 = 1,000 applications

Data Interpretation is an important part of Quantitative Aptitude because it tests how quickly you can read numbers and use them to solve problems. The Data Interpretation (DI) Questions for NICL AO may look lengthy, but the calculations often use basic maths.
The exact number of DI questions and marks can change with the exam pattern. As a preparation estimate, candidates may practise for around 2–3 DI sets, or approximately 10–15 questions, while checking the latest NICL AO notification and exam pattern for confirmed details.
Common Types of NICL AO DI Questions
Prepare these common formats:
- Table-Based DI: Data is shown in rows and columns. You may need to calculate totals, averages, ratios, or differences.
- Bar Graph DI: Bars compare numbers across categories, months, years, or products.
- Pie Chart DI: A circle shows how a total is divided into parts. Questions often involve percentages and ratios.
- Line Graph DI: A line shows changes over time, such as yearly sales or monthly production.
- Caselet DI: Data is provided in a paragraph. You must organise the information before solving the questions.
- Missing DI: One or more values are missing, and you need to calculate them using the available information.
- Mixed DI: Two formats, such as a table and a bar graph, may be used together.
Tip: Do not begin calculating immediately. First, read the title, labels, units, and values. Then identify exactly what the question asks.
Basic Rules to Solve NICL AO Data Interpretation Questions
Before attempting difficult sets, revise the basic calculations used in DI. Practise percentages, ratios, averages, and fractions until you can solve them quickly. Also, learn simple calculation tricks to reduce errors and save time during the exam.
| Calculation | Formula | Example |
| Percentage | (Part ÷ Total) × 100 | 20 out of 100 = 20% |
| Average | Total ÷ Number of values | 300 ÷ 3 = 100 |
| Ratio | Compare two quantities | 20 : 30 = 2 : 3 |
| Percentage Increase | (Increase ÷ Original value) × 100 | From 100 to 120 = 20% |
| Percentage Decrease | (Decrease ÷ Original value) × 100 | From 100 to 80 = 20% |
| Difference | Larger value − Smaller value | 90 − 50 = 40 |
Quick Method to Solve DI Questions
Step 1: Read the heading and understand what the data represents.
Step 2: Check the units, such as rupees, people, applications, or percentages.
Step 3: Identify the values needed to answer the question.
Step 4: Choose the correct calculation: addition, subtraction, multiplication, division, ratio, or percentage.
