## DI Questions with Solutions for Bank Exams – SBI PO,  IBPS PO

#### DI Questions Practice SET 1:

##### 1. Analyze the data from below given graph and pie-chart carefully to answer the questions that follow:

1.1) The Total number of employees in organization C is approximately what percent of total no. of employees in organization D?
(1) 147       (2) 279       (3) 312      (4) 207          (5) 183.

Solution:
31/ 15 = 207
Explanation:   100% of 15 = 15
200% of 15 = 30
10% of 15 = 1.5 i.e.      30 + 1 = 200% + 7% (approx.) = 207
Note: By practice we can able to do these calculations without using pen.

1.2) What is the total no. of males in all organization together?
Sol:
Average percentage of males = (30 + 55 + 60 + 40 +25) / 5 = 210 / 5 = 42%

• 42/100 × 35000
• 14700

1.3) What is the total number of males in organization A & C together?
Sol:
(18/ 100 × 30/100   + 31/100 × 60/100) × 35000
=> (540 + 1860) × 3.5
=> 2400 × 3.5
=> 240 × 35
=> 8400

1.4) What is the number of females in organization D?
(1) 3855       (2) 3250     (3) 3300     (4) 3675     (5) None of these

#### DI Questions Practice SET 2:

The Pie chart shows the population of various states in a certain year the total population is 60 lakhs.

The Population of Various States in a Certain Year.

The angles subtended at the center of the circle by different sectors are shown in degrees. The percentage of the total population represented by that sector.

Total Population = 60, 00,000.

The table below gives a gender-wise and literacy wise population ratio. Study the pie chart and the table and answer the questions that follow:

 State Gender Ratio Male: Female Literacy Ratio Literate: Illiterate A 4: 3 9: 4 B 5: 3 8: 5 C 3: 2 9: 5 D 3: 5 7: 3 E 9: 7 5: 2 F 3: 1 1: 3 G 7: 9 2: 1

(2.1) What is the approximate total of literates of States ‘B’ and ‘D’ together?

(a) 1288835
(b) 1289538
(c)  690462
(d) 694026
(e) None of these.

Solution: (literates of B) + (literates of D)
=> [(19 × 8/13) + (14 ×7/10)] × 60, 000.
=> [152 +1274] ×60, 000/130.
=> 1426 ×6000/13.
= 1289538

(2.2)  The number of females in ‘A’, ‘C’ and ‘E’ is what percentage of the total population of all the above states (‘A’, ‘B’, ‘C’, ‘D’, ‘E’, ‘F’, ‘G’)?

(a) 12.91%.
(b) 42.13%
(c) 21.91%
(d) 24.13%.
(e) None of these.

Solution:
Convert Degrees into percentage
Population of A = [82.8/360] ×100 = 23%
Population of C = [61.2/360] ×100 = 17%
Population of E = [43.2/360] ×100 = 12%
Females of A, C & E = [(23 × 3/7) + (17×2/5) + (12 ×7/16)]/100 × 60, 00, 000

No. of females of A, C & E is what % of total population
= [(69/7 + 34/5 + 84/16)/100] × 60, 00, 000/60, 00, 000
= [(69×80) + (102×34) + (35×84)/ (560)]/100
= [11928/560] × 100 = 21.91%

(2.3) If there be a decrease of 4% in the population of ‘E’ and an increase of 3% in the population of ‘F’, in the next year over the respective population of ‘F’ in the next year will be

(a) 163:128
(b) 125:101
(c) 123:103
(d) 128:103
(e) None of these.

Solution:
Present population of E = [43.2/360] ×6000000 = 7, 20, 000.
4% of 720000 = 28, 800.
Therefore, population of E next year = 7, 20, 000 – 28, 800 = 6, 91, 200
Present population of F = 9% of total population = 60, 00, 000 × 9/100 = 5, 40, 000
3% of population = 16, 200.
Therefore, population of F next year = 5, 40, 000 + 16, 200 = 5, 56, 200.
Therefore, Ratio of the population of E to the population of F next year
= 691200: 556200
= 128: 103 (approx.)

(2.4) The number of females in state F is approximately what percentage of the number of females in state ‘G’?

(a) 66.67%.
(b) 69.83%.
(c) 76.66%.
(d) 60.67%.
(e) None of these.

Solution:
The population of State F = 9% of the total population = 5, 40, 000.
= 9% of the total population = 5, 40, 000.
Therefore, number of females in State F = 540000 × 1/ 4.
= 1, 35, 000.
The population of Stage G
= 6% of the total population = 3, 60, 000
Therefore, number of females in stage G = 3, 60, 000 × 9/16 = 2, 02, 500.
Therefore, number of females in State F = ((135000/ 202500) × 100)
= 66.67%

(2.5) If 68.8% of the females and 72% of the males are literate in state ‘D’, then the ratio of male literates to female literates in that state is,

(a) 109: 329
(b) 189: 301
(c)  131: 301
(d) 103: 329
(e) None of these.

Solution: Population of State D = 14% of the total population = 8, 40, 000
Male: Female ratio is 3:5
Therefore, number of males = 840000 × 3/8 = 3, 15, 000
Therefore, number of females = 840000 × 5/8 = 5, 25, 000
72% of males is 2, 26,800.
68.8% of females are 3, 61,200.
Therefore, the ratio of male literates to female literates is 226800:361200 or
189: 301.

(2.6) What is the ratio of the illiterates of State ‘A’ to those of State ‘G’ approximately?

(a) 177: 50.
(b) 137: 65
(c) 183: 71
(d) 127: 73
(e) None of these.

Explanation:
Population of State A = 13, 80, 000.
Therefore, illiterates in State A
= 1380000 × 4/13 = 4, 24, 615.
Population of State G = 3, 60, 000
Therefore, illiterates in State G
360000 × 1/3 = 1, 20, 000

Illiterates in State A: Illiterates in State G = 177:50 (approx.)

#### Directions (1 to 5 Questions): Study the following graph and answer the questions.

5.1) What is the total (approx) number of cars sold in the year 2013 if the growth rate in the total number of cars sold from 2012 to 2013 was the same as that of 2011 to 2012?
(a) 23905
(b) 210978
(c) 24189.
(4) 26623
(5) 24659

Solution: Clue: Increase in the number of sales from 2012 to 2013 is same as 2011 to 2012

Increase in sales from 2011 to 2012  =  21568 – 19231 =2337.

Increase in sales from 2012 to 2013 is 2337

Therefore, Sales in 2013 = 21568 + 2337 = 23905

5.2) In which of the following years the ratio of the number of Maruti cars sold to the total number of cars sold was lowest?
(a) 2011
(b) 2006
(c) 2009
(d) 2008
(e) 2010

Trick:  Use approximations and guesswork for this question to save time

2006  -> 115: 27 => 11:3   ( In 2006, no. of manufacturing cars sold Maruti cars is lowest compared to other years).

2007 -> 126: 33  => 42: 11= 4: 1

2008 -> 140: 45   => 28: 9

2009 -> 150: 60  => 5: 2

2010 -> 170: 68

2011 -> 190: 70 => 19: 7

2012 -> 215: 99 =>2: 1

5.3) What was the approximate average number of cars sold (other than Maruti Cars) in a year, taking the data of all the years together?
(a) 11231
(b) 10317
(c) 10919
(d) 8778
(e) 12117

Explanation:

Sale of Cars Other than Maruthi Cars =  Total car sales – Maruthi Car sales

8826      |   9299   |  9410   |   9313   | 10309 | 12031  | 11668

Average = (8826 + 9299 + 9410 + 9313 + 10309 + 12031 +11668)/ 7  = 61446/7  = 8778

5.4) The number of Maruthi cars sold in the years 2007, 2008 and 2009 is approximate what percent of the total number of all the cars sold in the years 2006, 2007, 2009, 2011 and 2012?
(a) 22%
(b) 25%
(c) 17%
(d) 29%
(e) 11%

Solution:  Total no. of car sales (including Maruti cars) in 2006, 2007, 2009, 2011 and 2012 = (11526 + 12649 + 15313 + 19231 + 21568) = 80287.

Number of Maruthi cars sold in the years 2007, 2008 and 2009  = 13900.

Required Percentage = [13900/80287] * 100  = 17%

5.5) What is the ratio between the number of cars sold other than that of Maruti in 2011 to the total number of cars sold in 2006?
(a) 10: 26
(b) 10: 17
(c) 11: 4
(d) 11: 8
Solution:

Cars sold other than Maruthi cars in 2011  = (19231 -7200) =  12031

Cars sold other than Maruthi cars in 2006 = (11526 -2700) = 8826

Required Ratio = 12031 : 8826   =12000 : 8800  = 121 : 88  = 11: 8  (approximate)
