MCQ Test: Bar Graphs - 1 - Bank Exams MCQ

The sum of the number of people who visited Qutub Minar and India Gate in 2012 together = (360 + 300) = 660
The sum of the number of people who visited Lotus Temple and India Gate in 2013 together = (420 + 240) = 660
 Difference = (660 – 660) = 0
Hence, option E is correct.

The number of people who visited Qutub Minar and India Gate in 2013 together = (420 + 240) = 660
 The number of people who visited Lotus Temple and Taj Mahal in 2012 together = (320 +280) = 600
 Required ratio = 660 : 600 = 11 : 10
 Hence, option E is correct.

The number of people who visited Taj Mahal in 2013 = 450

The number of people who visited Taj Mahal and Lotus Temple in 2012 together = (280 + 320) = 600

Difference = (600 – 450) = 150

% less = 150/600 × 100 = 25%

Hence, option C is correct.

The difference between the number of people who visited Taj mahal in 2012 and 2013 = 450 – 320 = 130
% increased = 130/320 × 100 = 40.625%
The difference between the number of people who visited Qutub Minar in 2012 and 2013 = 420 – 360 = 60
% increased = 60/360 × 100 = 16.67%
The difference between the number of people who visited India Gate in 2012 and 2013 = 300 – 240 = 60
% decreased = 60-300 × 100 = 20%
The difference between the number of people who visited Lotus Temple in 2012 and 2013 = 420 – 280 = 140
% increased = 140/280 × 100 = 50%
Lotus Temple shows the maximum percentage increased in the number of people.
Hence, option B is correct.

Sum of the number of people who visited Taj Mahal in 2012, Qutub Minar in 2012, Lotus Temple in 2013 and India Gate in 2013 = (320 + 360 + 420 + 240) = 1340

Reqd. average = 1340/4 = 335

Hence, option A is correct.

Calculation:

There will be a total of 41 members in the factory = 39 workers + 2 managers

Daily wages of the managers ranges between 700 and 800, it would be calculated on the basis of 750.

Similarly, the calculation would be done according to the midpoints (for eg. if 5  employees have their salaries between 200 to 300, it will be solved as 5 × 250)

Total daily wages of all members of staff of the factory = 250 × 5 + 350 × 9 + 450 × 12 + 550 × 11 + 650 × 2 + 750 × 2 = Rs.18650

Total number of workers = 5 + 9 + 12 + 11 + 2 + 2 = 41

∴ the average daily wage of all members of staff of the factory = 18650/41 = 454.8 ≈ Rs.455

Calculation:

Production of raw wool in 2014-15 = 51

Production of raw wool in 2019-20 = 68

Required production of raw wool = (51/68)

⇒ 3/4

∴ Required production of raw wool is 3/4

Calculation:

TV sets manufactured by company C = 70000

TV sets sold by company C = 82% of 70000 = 57400

TV sets manufactured by company D = 85000

TV sets sold by company D = 56% of 85000 = 47600

Total TV sold by C and D = 57400 + 47600 = 105000

Average TV sold by C and D = 105000/2 = 52500

TV sets manufactured by company E = 58000

Now, % = 52500/58000 × 100% ≈ 90.5%

∴ The average number of TV sets sold by companies C and D is 90.5% of the number of TV sets manufactured by company E.

Given:-

Athletic club of 232 members and their height's frequency.

Concept used:-

Frequency Polygon:-  A frequency polygon is a graph constructed by using lines to join the midpoints of each interval or bin. The heights of the points represent the frequencies. A frequency polygon can be created from the histogram or by calculating the midpoints of the bins from the frequency distribution table.

Formula Used:

Class size = Upper limit - Lower limit

Calculation:

From histogram -

Class size = Upper limit - Lower limit

Class size = 125 - 120 = 5

∴ Mid point of a class = 5/2 = 2.5

So, Starting point of Line graph -

X - co-ordinate = 120 - 2.5 = 117.5

Y - co-ordinate = frequency of point = 0

∴ Starting point = (117.5,0)

End point of Line graph -

X - co-ordinate = 170 + 2.5 = 172.5

Y - co-ordinate = frequency of point =  0

∴ End point = (172.5,0)

∴ Required points are (117.5,0) and (172.5,0).

Calculation:

Female in Q = 1240 - 350 = 890

Female in S = 825 - 340 = 485

According to the question:

Sum = 890 + 485 = 1375

∴ Option 3 is the correct answer.

The reqd. answer is = 18000/40 = 450
Hence, option B is correct.

Number of units of product D = 30/25 × 450 = 540

Total Cost price = Rs. 25 × 540 = Rs. 13500

35% units of product D were damaged and sold at Rs.12/unit ,

So total SP of damaged products = 35% of 540 × 12 = Rs. 2268

Total SP of remaining products of D = 65% of 540 × 30 = Rs. 10530

Total loss = Rs. (13500 – 2268 – 10530) = Rs. 702

Hence option A is correct.

Number of units of product C = 10/25 × 450 = 180

The cost price of product C per unit
= 8100/180 = Rs.45

The selling price to gain a 20% profit

= 120/100 × 45 = Rs.54/unit

Hence, Option B is correct.

No. of units of product A sold = 18000/40 = 450
So total products sold = 

No. of units of products B sold = 

The profit made = (270 × 25) = Rs. 6750

Hence, option A is correct.

The required ratio is = 25 : 20 = 5 : 4
Hence, Option D is correct.

Total sale of Samsung = 500 + 350 = 850

Total sale of Whirlpool = 320 + 270 = 590


Hence, option C is the correct answer.

Machines sold by Samsung, Godrej and Videocon of price more than Rs. 10000 = 350 + 180 + 230 = 760

Average = 760/3 = 253.3

Machines sold by LG and Whirlpool of price up to Rs. 10000

= 450 + 320 = 770

Average = 770/2 = 385

Required difference = 385 – 253.3 = 131.7

Hence, option E is the correct answer.

Washing machines of price up to Rs. 10000
 that were sold in the festival = 500 + 450 + 250 + 320 + 220 = 1740
 Hence, option B is the correct answer.

Total machines sold by LG and Godrej together of price upto Rs. 10000 = 450 + 250 = 700

Total machines sold by Videocon and Whirlpool together of price more than Rs. 10000 = 230 + 270 = 500

Reqd. ratio = 700/500 = 7 : 5

Hence, option A is the correct answer.

Samsung machines sold = 500 + 350 = 850
 LG machines sold = 450 + 400 = 850
 Whirlpool machines sold = 320 + 270 = 590
 Godrej machines sold = 250 + 180 = 430
 Samsung and LG sold same number of machines.
 Hence, option E is the correct answer.
