Answer (Detailed Solution Below)
Data Interpretation Question 1 Detailed Solution
General Solution:
Given: Total number of firefighters across all districts = 4200
Let the total number of firefighters in terms of x be:
District A = 6x
District B = 7.2x
District C = 9x
District D = 9.6x
District E = 10.2x
Add total firefighters across all districts:
6x + 7.2x + 9x + 9.6x + 10.2x = 42x
⇒ 42x = 4200
⇒ x = 4200 ÷ 42 = 100
Calculate total firefighters in each district using x = 100:
District A = 6 × 100 = 600
District B = 7.2 × 100 = 720
District C = 9 × 100 = 900
District D = 9.6 × 100 = 960
District E = 10.2 × 100 = 1020
Use difference between full-time and volunteer firefighters:
District A: Total = 600, Difference = 288
⇒ Let volunteer = a, then full-time = a + 288
⇒ a + (a + 288) = 600 ⇒ 2a + 288 = 600
⇒ 2a = 312 ⇒ a = 156
⇒ Volunteer = 156, Full-time = 444
District B: Total = 720, Difference = 120
⇒ Let volunteer = a, full-time = a + 120
⇒ 2a + 120 = 720 ⇒ 2a = 600 ⇒ a = 300
⇒ Volunteer = 300, Full-time = 420
District C: Total = 900, Difference = 180
⇒ Let volunteer = a, full-time = a + 180
⇒ 2a + 180 = 900 ⇒ 2a = 720 ⇒ a = 360
⇒ Volunteer = 360, Full-time = 540
District D: Total = 960, Difference = 336
⇒ Let volunteer = a, full-time = a + 336
⇒ 2a + 336 = 960 ⇒ 2a = 624 ⇒ a = 312
⇒ Volunteer = 312, Full-time = 648
District E: Total = 1020, Difference = 60
⇒ Let volunteer = a, full-time = a + 60
⇒ 2a + 60 = 1020 ⇒ 2a = 960 ⇒ a = 480
⇒ Volunteer = 480, Full-time = 540
Thus,
| District | Total | Full-time | Volunteer |
|---|---|---|---|
| A | 600 | 444 | 156 |
| B | 720 | 420 | 300 |
| C | 900 | 540 | 360 |
| D | 960 | 648 | 312 |
| E | 1020 | 540 | 480 |
Calculations:
Given:
Total firefighters in District A = 600
Total firefighters in District A + District Y = 1500
Find total firefighters in District Y:
⇒ Y = 1500 - 600 = 900
Full-time firefighters in District B = 420 (from general solution)
Find the difference:
⇒ Difference = Firefighters in Y - Full-time in B
⇒ Difference = 900 - 420 = 480
Thus, the correct answer: 480

Answer (Detailed Solution Below)
Data Interpretation Question 2 Detailed Solution
General Solution:
Given: Total number of firefighters across all districts = 4200
Let the total number of firefighters in terms of x be:
District A = 6x
District B = 7.2x
District C = 9x
District D = 9.6x
District E = 10.2x
Add total firefighters across all districts:
6x + 7.2x + 9x + 9.6x + 10.2x = 42x
⇒ 42x = 4200
⇒ x = 4200 ÷ 42 = 100
Calculate total firefighters in each district using x = 100:
District A = 6 × 100 = 600
District B = 7.2 × 100 = 720
District C = 9 × 100 = 900
District D = 9.6 × 100 = 960
District E = 10.2 × 100 = 1020
Use difference between full-time and volunteer firefighters:
District A: Total = 600, Difference = 288
⇒ Let volunteer = a, then full-time = a + 288
⇒ a + (a + 288) = 600 ⇒ 2a + 288 = 600
⇒ 2a = 312 ⇒ a = 156
⇒ Volunteer = 156, Full-time = 444
District B: Total = 720, Difference = 120
⇒ Let volunteer = a, full-time = a + 120
⇒ 2a + 120 = 720 ⇒ 2a = 600 ⇒ a = 300
⇒ Volunteer = 300, Full-time = 420
District C: Total = 900, Difference = 180
⇒ Let volunteer = a, full-time = a + 180
⇒ 2a + 180 = 900 ⇒ 2a = 720 ⇒ a = 360
⇒ Volunteer = 360, Full-time = 540
District D: Total = 960, Difference = 336
⇒ Let volunteer = a, full-time = a + 336
⇒ 2a + 336 = 960 ⇒ 2a = 624 ⇒ a = 312
⇒ Volunteer = 312, Full-time = 648
District E: Total = 1020, Difference = 60
⇒ Let volunteer = a, full-time = a + 60
⇒ 2a + 60 = 1020 ⇒ 2a = 960 ⇒ a = 480
⇒ Volunteer = 480, Full-time = 540
Thus,
| District | Total | Full-time | Volunteer |
|---|---|---|---|
| A | 600 | 444 | 156 |
| B | 720 | 420 | 300 |
| C | 900 | 540 | 360 |
| D | 960 | 648 | 312 |
| E | 1020 | 540 | 480 |
Calculations:
Given for District E:
Total firefighters = 1020
Full-time = 540
Volunteer = 480
80% are rural ⇒ 80% of 1020 = (80/100) × 1020 = 816
Urban firefighters = 1020 - 816 = 204
Ratio of full-time to volunteer urban firefighters = 5 : 7
Let urban full-time = 5a and urban volunteer = 7a
⇒ 5a + 7a = 12a = 204 ⇒ a = 17
⇒ Urban full-time = 5 × 17 = 85
⇒ Urban volunteer = 7 × 17 = 119
Find rural firefighters:
Total full-time in E = 540
Urban full-time = 85
⇒ Rural full-time = 540 - 85 = 455
Thus, the correct answer: 455

Given: Total number of firefighters across all districts = 4200
Let the total number of firefighters in terms of x be:
District A = 6x
District B = 7.2x
District C = 9x
District D = 9.6x
District E = 10.2x
Add total firefighters across all districts:
6x + 7.2x + 9x + 9.6x + 10.2x = 42x
⇒ 42x = 4200
⇒ x = 4200 ÷ 42 = 100

Average full-time firefighters in districts A, B, and G = 340
Total full-time in A = 444 (from earlier)
Total full-time in B = 420 (from earlier)
Total firefighters in G = 20% more than in A
Use average formula:
⇒ 864 + G = 1020
⇒ G (full-time in G) = 1020 - 864 = 156
Find total firefighters in district G:
Total in A = 600
⇒ Total in G = 600 + 20% of 600 = 600 + 120 = 720
Find volunteer firefighters in G:
Total = Full-time + Volunteer
⇒ Volunteer = Total - Full-time = 720 - 156 = 564
Thus, the correct answer: 564

| Initial calls(% out of total calls) | 40% | 30% | 30% |
| Lead calls (% out of initial calls) | 80% | x% | 88% |
| Final received calls(% out of lead calls) | 90% | 80% | y% |
Total number of initial calls in the company is 24000 and total number of calls not received by company C is 4464 less than the total number of calls received by company A. Find the value of y.
Answer (Detailed Solution Below)
Data Interpretation Question 6 Detailed Solution
Download Solution PDFCalculation:
Let the total number of calls be 1000z.
Initial calls (% out of total calls) of A = (1000z × 40/100) = 400z
Initial calls (% out of total calls) of B = (1000z × 30/100) = 300z
Initial calls (% out of total calls) of C = (1000z × 30/100) = 300z
Lead calls (% out of initial calls) of A = (400z × 80/100) = 320z
Lead calls (% out of initial calls) of B = (300z × x/100) = 3zx
Lead calls (% out of initial calls) of C = (300z × 88/100) = 264z
Final received calls (% out of lead calls) of A = (320z × 90/100) = 288z
Final received calls (% out of lead calls) of B = (3zx × 80/100) = 3zx × (4/5)
Final received calls (% out of lead calls) of C = (264z × y/100)
Total number of initial calls in the company = 24000
⇒ (400z + 300z + 300z) = 24000
⇒ 1000z = 24000
⇒ z = (24000/1000)
⇒ z = 24
Total number of calls not received calls by C = (300h – 264z × y/100)
⇒ (300 × 24 – 264z × y/100)
⇒ (7200 – 264z × y/100)
According to the question
Total number of calls not received by company C is 4464 less than the total number of calls received by company A
⇒ (7200 – 264z × y/100) + 4464 = 288z
⇒ (7200 – 264 × 24 × y/100) + 4464 = 288 × 24
⇒ 7200 – 6336y/100 + 4464 = 6912
⇒ (720000 – 6336y + 446400)/100 = 6912
⇒ (720000 – 6336y + 446400) = 6912 × 100
⇒ (1166400 – 6336y) = 691200
⇒ (-6336y) = (691200 – 1166400)
⇒ (-6336y) = -475200
⇒ y = [-475200/(-6336)]
⇒ y = 75
∴ The value of y is 75

Calculate the average family size from the given data.
Answer (Detailed Solution Below)
Data Interpretation Question 9 Detailed Solution
Download Solution PDFCalculation:
Number of families having 1 member = 5
Total members = 5
Number of families having 2 members = 30
Total members = 60
Number of families having 3 members = 45
Total members = 135
Number of families having 4 members = 40
Total members = 160
Number of families having 5 members = 25
Total members = 125
Number of families having 6 members = 5
Total members = 30
So, the total membes in all types of families = 5 + 60 + 135 + 160 + 125 + 30 = 515
Total number of families = 5 + 30 + 45 + 40 + 25 + 5 =150
The average family size = 515 / 150 = 3.4
Hence, option 3 is correct.

Let the Cost price of the book be 100
Then, Marked Price of the book is 100 + (15% of 100) = 115
Printed price or marked price = 942
Cost price of book = 942 × (100/115)
⇒ 819.13
Now,
Paper cost = 819.13 × 15/100
⇒ 122.869 ≈ 122.9
∴ The required answer is Rs. 122.9

From the chart
Profit percentage in P5 = 8%
Expenditure = Rs. 46000
FORMULA USED:
Profit percentage = [(Revenue – Expenditure)/Expenditure] × 100
CALCULATION:
Profit percentage = [(Revenue – Expenditure)/Expenditure] × 100
⇒ 8 = [(Revenue – 46000)/46000] × 100
⇒ Revenue – 46000 = 8 × 460
⇒ Revenue = 3680 + 46000
⇒ Revenue = 49680

Find the percentage of total revenue which comes from Cooler from shop E, considering all given items are being sold from shop E and from all the given shops only given three items are being sold. (Rounded off to three decimal places)
Answer (Detailed Solution Below)
Data Interpretation Question 14 Detailed Solution
Download Solution PDFCalculation:
Total cooler sold by shop E = 4000 × (1/10)
⇒ 400
Selling price of 400 coolers = 400 × 8000
⇒ 3200000
Total ACs sold by shop E = 4000 × (5/10)
⇒ 2000
Selling price of 2000 ACs = 2000 × 26500
⇒ 53000000
Total Fans sold by shop E = 4000 × (4/10)
⇒ 1600
Selling price of 1600 Fans = 1600 × 12200
⇒ 19520000
Now,
Required % = [3200000/(3200000 + 53000000 + 19520000)] × 100
⇒ [3200000/(75720000)] × 100
⇒ 4.226 ≈ 4.23%
∴ The required answer is 4.23%.
