Directions: Read the data carefully and answer the following questions. 

Below is the bar graph which shows the number of books sold by four different shops P, Q, R and S on Saturday. 

If shop P and Q combined, sold 25% of their total books to online customers, how many total books were sold to offline customers by shop P and Q combined?

View answer & explanation

Correct answer

Answer: (b)B.

51

Why this answer is correct

Given Data:

Shop P sold 32 books

Shop Q sold 36 books

Total books P + Q = 32 + 36 = 68

Online sales = 25% × 68 = 0.25 × 68 = 17

Offline sales = Total books - Online sales = 68 - 17 = 51

Thus, 51 books were sold to offline customers by Shop P and Q combined.

View answer & explanation

Correct answer

Answer: (a)A.

49:47

Why this answer is correct

From the table:

Tasks completed by B in April = 45

Tasks completed by D in April = 53

Total tasks completed by B and D together in April:

45 + 53 = 98

From the table:

Tasks completed by A in March = 53

Tasks completed by C in March = 41

Total tasks completed by A and C together in March:

53 + 41 = 94

The ratio of tasks completed by B and D together in April to tasks completed by A and C together in March is:

98 / 94 = 49 / 47

Thus, the ratio is 49:47.

    13.33%

  5. EOption (e)

    0%

View answer & explanation

Correct answer

Answer: (a)A.

20%

Why this answer is correct

From the table:

March: 41

April: 69

May: 28

June: 42

Total tasks by C:

41 + 69 + 28 + 42 = 180

From the table:

March: 33

April: 45

May: 37

June: 35

Total tasks by B:

33 + 45 + 37 + 35 = 150

Difference = Total tasks by C - Total tasks by B = 180 - 150 = 30

The percentage difference is calculated relative to the total tasks completed by B:

Percentage Difference =Difference / Total tasks by B × 100 = 30 / 150 × 100 = 20%

Thus, the number of tasks completed by Person C in all months is 20% more than the number of tasks completed by Person B in all months.

50

Why this answer is correct

From the table, the number of tasks completed by each person in April is:

A: 23

B: 45

C: 69

D: 53

Total tasks in April:

23 + 45 + 69 + 53 = 190

From the table, the number of tasks completed by each person in May is:

A: 40

B: 37

C: 28

D: 35

Total tasks in May:

40 + 37 + 28 + 35 = 140

Difference = Total Tasks in April Total Tasks in May = 190 - 140 = 50

Thus, the difference between the number of tasks completed by all in April and May is 50.

View answer & explanation

Correct answer

Answer: (b)B.

100%

Why this answer is correct

From the table:

Tasks completed by A in March = 53

Tasks completed by A in April = 23

Tasks completed by A in May = 40

Tasks completed by A in June = 54

Total tasks completed by A:

53 + 23 + 40 + 54 = 170

From the table:

Tasks completed by A in June = 54

Tasks completed by B in June = 35

Tasks completed by C in June = 42

Tasks completed by D in June = 39

Total tasks completed by all persons in June:

54 + 35 + 42 + 39 = 170

Percentage = Tasks by A / Tasks by All in June × 100 = 170 / 170 × 100 = 100%

Thus, the number of tasks completed by Person A in all months is 100% of the tasks completed by all persons in June.

Correct answer

Answer: (a)A.

311

Why this answer is correct

GIVEN:

11.11% of 819 + 55% of 800 = ?

FORMULA USED:

These types of questions, the knowledge of conversion from percentage to fraction should be known.

Fraction2/311/203/201/9
Percentage (%)66.66551511.11

 

Concept :

Follow BODMAS rule to solve this question, as per the order given below.

Step - 1: Parts of an equation enclosed in 'Brackets' must be solved first, and following BODMAS rule in the bracket -

Step - 2: Any mathematical 'Of' or 'Exponent' must be solved next.

Step - 3: Next, the parts of the equation that contain 'Division' and 'Multiplication' are calculated.

Step - 4: Last but not the least, the parts of the equation that contain 'Addition' and 'Subtraction' should be calculated.

CALCULATION:

11.11% of 819 = (1/9) × 819 = 91

55% of 400 = (11/20) × 400 = 220

Given expression is

11.11% of 819 + 55% of 400 = ?

⇒ 91 + 220 = ?

⇒ 311 = ?

∴ ? = 311
