Introduction to Data Interpretation problems
- 1. For the candidates from which of the following locations was there continuous increase both in appeared and passed?
Options- A. Semi-urban
- B. State capital
- C. State capital and Rural
- D. Metropolises Discuss
Correct Answer: Metropolises
Explanation:
As we can see in the graph that metropolises location has continuous increase both in appeared and passed.
- 2. In which of the following years was the percentage passed to appeared candidates from semi-urban area the least?
Options- A. 1991
- B. 1993
- C. 1990
- D. 1992 Discuss
Correct Answer: 1990
Explanation:
Our intelligent observation says that the required year cannot be 1993, 1994, 1995. Why? Because see the following conclusions:
% passed to appear = Passed / Appeared x 100
% of passed to appear is least when Passed / Appeared is the least or, Appeared / Passed is the most.
Now, we do the further calculations mentally. See the following conclusions:
For 1990: 7894 / 2513 ? Quotient = 3 and Remainder ? 300
For 1991: 8562 / 2933 ? Q = 3 and R ? 400
For 1992: 8139 / 2468 ? Q = 3 and R ? 800
Similarly, for 1993; 1994, 1995, Q is 2.
So, 1992 gives the highest value.
- 3. What approximate value was the percentage drop in the number of semi-urban candidates appeared from 1991 to 1992?
Options- A. 5
- B. 10
- C. 15
- D. 8 Discuss
Correct Answer: 5
Explanation:
- 4. In 1993 percentage of candidates passed to appeared was approximately 35 from which location?
Options- A. Rural
- B. Rural and Metropolises
- C. Semi-urban and Metropolises
- D. Rural and Semi-urban Discuss
Correct Answer:
Explanation:
We do not need to calculate the values for each year.
Follow as:
For Rural area : 35% of 5032 ? 35 × 50 = 1750 ? 1798
For Semi-urban area : 35% of 9500 ? 35 × 95 ? 3300
Which cannot be approximated to 3500.
For State capitals : 35 × 85 = 3000
For Metropolises : 35 × 110 = 3850
- 5. The total number of candidates passed from Rural in 1993 and Semi-urban in 1990 was exactly equal to the total number of candidates passed from State capital in which of the following years?
Options- A. 1990
- B. 1993
- C. 1994
- D. 1992 Discuss
Correct Answer: 1994
Explanation:
The total number of candidates passed = Candidates passed from Rural in 1993 + Candidates passed from Semi-urban in 1990
The total number of candidates passed = 1798 + 2513 = 4311.
From the given table graph check the number of passed candidate from state capital is 4311 which is 1994.
- 6. What was the difference between the number of B type tyres manufactured in 1994 and 1995?
Options- A. 100000
- B. 2000000
- C. 1000000
- D. 1500000 Discuss
Correct Answer:
Explanation:
Required difference = Number of B type tyres in 1994 - Number of B type tyres in 1995
Required difference = ( 27.5 ? 22.5 ) Million = 5 Million = 5000000.
- 7. The total number of all the three types of tyres manufactured was the least in which of the following years?
Options- A. 1995
- B. 1996
- C. 1992
- D. 1994 Discuss
Correct Answer: 1995
Explanation:
Only by visual observation you can find the answer. You do not need to calculate the values. I (iv) (e) Production of B type cars is more than the production of C type cars only in 1993, 1994 and 1995. We see the largest difference exists in 1995. So, the answer is 1995.
- 8. The total production of C type tyres in 1992 and 1993 together was what percentage of production of B type tyres in 1994?
Options- A. 50
- B. 100
- C. 150
- D. 200 Discuss
Correct Answer: 200
Explanation:
- 9. What was the percentage drop in the number of C type tyres manufactured from 1993 to 1994?
Options- A. 25
- B. 10
- C. 15
- D. 25 Discuss
Correct Answer: 25
Explanation:
- 10. In which of the following years was the maximum production of C type?
Options- A. 1994
- B. 1992
- C. 1996
- D. 1993 Discuss
Correct Answer:
Explanation:
As we can see in the graph the maximum chart for the C is in 1995.
