The total number of students in Std. 6 and Std. 9 together is approximately what percentage more than that of the total number of students in Std. 10?

  1. 66%
  2. 387%
  3. 187%
  4. 78%
  5. None of the above

Answer (Detailed Solution Below)

Option 3 : 187%

Line Graph Question 1 Detailed Solution

Calculation:

The percentage of students in Std. 6 and Std. 9

Std. 6: 25%

Std. 9: 18%

Total: 25% + 18% = 43%

The percentage of students in Std. 10

Std. 10: 15%

The difference between the two percentages = 43% - 15% = 28%

Percentage increase = 28/15 x 100% = 186.66% ≈ 187%

∴ Option (3) is the correct answer.

What is the difference between the total number of students in Std. 7 and Std. 8 together to that of the total number of students in Std. 9 and Std. 10 together?

  1. 308
  2. 302
  3. 198
  4. 415
  5. None of the above

Answer (Detailed Solution Below)

Option 3 : 198

Line Graph Question 2 Detailed Solution

Calculation:

Total percentages of students in Std. 7 and 8 are = 30 + 12 = 42%

Total percentages of students in Std. 8 and 10 are = 18 + 15 = 33%

Net difference = 42 - 33 = 9% of total students

The difference of students between the respective standards = 2200 × 9/100 = 198

∴ Option (3) is the correct answer.

The total number of boys in Std. 8 is "x" and the total number of boys in Std. 9 is “x + 40". If the total number of girls in Std. 8 and Std. 9 together is 120, then find the value of “x".

  1. 210
  2. 190
  3. 250
  4. 270
  5. None of the above

Answer (Detailed Solution Below)

Option 3 : 250

Line Graph Question 3 Detailed Solution

Given:

The total number of boys in Std. 8 is "x"

The total number of boys in Std. 9 is “x + 40"

The total number of girls in Std. 8 and Std. 9 together is 120

Calculation:

Total students in std. 8 are = 2200 × 12/100 = 264

So, total girls in std. 8 are = (264 - x)

Total students in std. 9 are = 2200 × 18/100 = 396

So, total girls in std. 9 are = 396 - (x + 40)

According to the question,

(264 - x) + 396 - (x + 40) = 120

⇒ 264 - x + 356 - x = 120

⇒ 2x = 500

⇒ x = 250

∴ The value of x is 250.

If in Std. 6, the ratio of boys to girls is 6 ∶ 5 and the total number of girls in Std. 6 is 50 less than that of the total number of girls in Std. 7, then find the ratio of the total number of boys in Std. 6 to Std. 7.

  1. 5 ∶ 6
  2. 30 ∶ 47
  3. 6 ∶ 17
  4. 17 ∶ 6
  5. None of the above

Answer (Detailed Solution Below)

Option 1 : 5 ∶ 6

Line Graph Question 4 Detailed Solution

Given:

In Std. 6, the ratio of boys to girls is 6 ∶ 5

The total number of girls in Std. 6 is 50 less than that of the total number of girls in Std. 7

Calculation:

Total students in Std. 6 = 2200 × 25/100 = 550

Total boys in Std. 6 = 550 × 6/(6 + 5) = 300

Total girls in Std. 6 = 550 × 5/(6 + 5) = 250

According to the question,

Total girls in Std. 7 = 250 + 50 = 300

Total students in Std. 7 are = 2200 × 30/100 = 660

So, total boys in Std. 7 are = 660 - 300 = 360

The ratio of the total number of boys in Std. 6 to Std. 7 = 300 : 360 = 5 : 6

∴ The ratio of the total number of boys in Std. 6 to Std. 7 is 5 : 6.

If in 2024, the total number of students in Std. 6 and Std. 7 is increased by 10% each and the total number of students in Std. 10 is decreased by 20%, then what is the difference between the total number of students in Std. 6 and 7 together in 2023 to that of the total number of students in Std. 10 in 2024 ? 

  1. 1056
  2. 946
  3. 1067
  4. 1078
  5. None of the above

Answer (Detailed Solution Below)

Option 2 : 946

Line Graph Question 5 Detailed Solution

Given:

In 2024, the total number of students in Std. 10 is decreased by 20%

Calculation:

In 2023, total students in Std. 6 and Std. 7 are = 2200 × (25 + 30)/100 = 1210

In 2023, students in Std. 10 are = 2200 × 15/100 = 330

In 2024, students in Std. 10 are = 330 × (100 - 20)/100 = 264

The total number of students in Std. 6 and 7 together in 2023 = (1210 - 264)

⇒ 946 more than the total students in Std. 10 in 2024

∴ Option (2) is the correct answer.

Download Solution PDF

GIVEN:

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

Calculation:

Total value of vehicles manufactured by company A during 2010 - 2015 = 260 + 218 + 224 + 179 + 266 + 348 = 1495

Average value of vehicles manufactured by company A during 2010 - 2015 = 1495/6 = 249.16 (in thousands)

Total value of vehicles manufactured by company B during 2010 - 2015 = 307 + 270 + 250 + 289 + 310 + 416 = 1842

Average value of vehicles manufactured by company B during 2010 - 2015 = 1842/6 = 307 (in thousands)

∴ Required percentage = 249.16/307 × 100 = 81.2%

Given:

The revenue of product P3 is Rs. 38100.

Formula used:

Profit% = (revenue – expenditure)/expenditure × 100

Calculation:

The revenue of product P3 is 38100,

Let expenditure be Rs. y.

⇒ Profit% = (revenue – expenditure)/expenditure × 100

⇒ 27 = (38100 – y)/y × 100

⇒ 27y = 3810000 – 100y

⇒ 127y = 3810000

⇒ y = 30000

∴ Expenditure of product P3 is Rs. 30000

Line Graph Question 10 Detailed Solution

Download Solution PDF

Calculation:

Manufacturing capacity of plant A = 420 + 140 = 560

Manufacturing capacity of plant B = 350 + 150 = 500

Manufacturing capacity of plant C = 360 + 120 = 480

Manufacturing capacity of plant D = 440 + 80 = 520

Manufacturing capacity of plant E = 440 + 110 = 550

So,

Plant A has the highest manufacturing capacity.

In Plant A:

Local Quality = 420

Export Quality = 140

Thus, 

Local quality : Export quality

⇒ 420 : 140 = 3 : 1

∴ The correct answer is option (1).

Line Graph Question 13 Detailed Solution

Download Solution PDF

Calculation:

Ratio of export to import in 2010 = E : I = 9 : 10

Ratio of export to import in 2011 = E : I = 12 : 10

Ratio of export to import in 2012 = E : I = 7 : 10

Ratio of export to import in 2013 = E : I = 24 : 10

Ratio of export to import in 2014 = E : I = 35 : 10

Ratio of export to import in 2015 = E : I = 24 : 10

Hence, there are four observations in which the export of company A was more than the company A import

∴ The correct answer is four.

From the graph:

CO2 concentration in the year 1995 = 360

CO2 concentration in the year 2015 = 400

Hence,

Percentage change = [(400 – 360)/360] × 100

⇒ 40/360 × 100

⇒ 1/9 × 100 = 11.11%

∴ The percentage change in COconcentration is 11.11%.
