**In this article, we learn how we can calculate DI questions easily by solving most repeatedly asked pattern in our examinations**

**Guidelines:**

- When two diagrams are found they will be interlinked
- These are of three patterns of asking questions
- 1) question directly about diagram 1
- 2) question directly about diagram 2
- 3) question indirectly about both diagrams
- Study the given data to have a rough idea
- Try to find the difference between two diagrams
- Remember the two diagrammatic relations (1st – no of train accidents, 2nd – number of persons) it becomes easy while reading the question.
- Try to solve DI questions by visual Inspection and mind calculation.

**Study the pie-chart and line graph carefully to answer the given questions**

**The pie-chart shows the percentage of train accidents in different years**

**The line graph shows the number of persons who died in train accidents in various states in different years**

### Question 1.

**The number of persons who died in train accidents in 2013 is how much percent more than the number of persons who died in the train accident in 2011?**

a) 143.5%

b) 137.5%

c) 37.5%

d) 127.5%

e) 147.5%

**Ans.C**

**Trick to solve easily:**

(2013-2011)/2011 * 100

600/1600 * 100 = 37.5

**Explanation:**

(2013-2011) = (700-700 + 600-200 + 500-600 + 400-100) = (400-100+300) = 600

2011 = (7+6+2+1) * 100 = 1600

(2013-2011)/2011 = 600/1600 = 37.5%

### Question 2.

**What is the average of the number of persons who died in train accidents in 2008 in all states together?**

a) 182

b) 290

c) 275

d) 284

e) 307

**Ans.C**

**Trick to solve easily:**

Solve by visual Inspection

(1100/4) = 275

**Explanation:**

(500+300+200+100)/4 = 275

### Question 3.

**In which state is the number of persons who died in the train accidents the maximum during the given period?**

a) Odisha

b) UP

c) Bihar

d) Only a) and b)

e) Maharashtra

**Ans.B.**

**Trick to solve easily:**

Solve by visual Inspection

**Explanation:**

Odisha = (3+2+7+6+4+5+2)*100 = 2900

Up = (5+6+5+7+6+7+6) * 100 = 4200

Maharashtra = (2+4+1+1+3+4+3) * 100 = 1800

Bihar = (1+3+3+2+5+6+4) * 100 = 2400

### Question 4.

**What is the difference between the number of train accidents in 2014 and that in 2012?**

a) 5

b) 6

c) 7

d) 8

e) 9

**Ans. D.**

**Trick to solve easily:**

(18-14) = 4% of 200 = 8

### Question 5.

**What is the ratio of the number of persons who died in train accidents in 2010 to that in 2014?**

a) 8 : 7

b) 10 : 9

c) 12 : 11

d) 14 : 13

e) 16 : 15

**Ans.E.**

**Trick to solve easily:**

(1+3+5+7) : (2+3+4+6) = 16:15
