Common Calculation

In 2016 Ore extraction by X = 150 kg

A type ore extraction by X = 150 × [40 /100] = 60 kg

B type ore extraction by X = 150 – 60 = 90 kg

Ore extraction by Y = 90 kg

A type ore extraction by Y = 90 - 30 = 60 kg

B type ore extraction by Y = 30 kg

Similarly, we can calculate the others data also.

Calculation

A-type ore by Y in 2016 and 2018 = 60 + 45 = 105
B-type ore by X in 2018 and 2019 = 140 + 60 = 200

Required Percentage

[105/ 200] × 100 = 52.5%

Common Calculation

In 2016 Ore extraction by X = 150 kg

A type ore extraction by X = 150 × [40 /100] = 60 kg

B type ore extraction by X = 150 – 60 = 90 kg

Ore extraction by Y = 90 kg

A type ore extraction by Y = 90 - 30 = 60 kg

B type ore extraction by Y = 30 kg

Similarly, we can calculate the others data also.

Calculation

Average A-type ore by X in 2016, 2017, 2021 = 73
⇒ Total = 73 × 3 = 219

From 2016 and 2017:

So, 60+90=150

⇒ A-type in 2021=219−150=69

Total ore by Company Y in 2019 = 70 (A) + 90 (B) = 160

Total ore by Company X in 2021 = 1.5 × 160 = 240

⇒ B-type in 2021 = Total - A-type = 240 - 69 = 171 kg

Common Calculation

In 2016 Ore extraction by X = 150 kg

A type ore extraction by X = 150 × [40 /100] = 60 kg

B type ore extraction by X = 150 – 60 = 90 kg

Ore extraction by Y = 90 kg

A type ore extraction by Y = 90 - 30 = 60 kg

B type ore extraction by Y = 30 kg

Similarly, we can calculate the others data also.

Calculation

Let B-type ore by Company X in 2015 = 13x
Then, in 2017 = 18x
From table: 2017 B-type = 90
So, 18x = 90

⇒ x=5

⇒ 2015 B-type = 13x = 65

Let 2015 A-type = y
Then, A-type in 2019 = y + 20% of y = 1.2y
From table: 2019 A-type = 180

⇒ 1.2y = 180

⇒ y= 150

Total ore by X in 2015 = A + B = 150 + 65 = 215

Total ore by Y in 2018 = A + B = 45 + 75 = 120

Ratio = 215/120=43:24
Answer: 43:24

Common Calculation

In 2016 Ore extraction by X = 150 kg

A type ore extraction by X = 150 × [40 /100] = 60 kg

B type ore extraction by X = 150 – 60 = 90 kg

Ore extraction by Y = 90 kg

A type ore extraction by Y = 90 - 30 = 60 kg

B type ore extraction by Y = 30 kg

Similarly, we can calculate the others data also.

Calculation

A-type ore by Y in 2022

66⅔% more than 2016 = 60

66⅔% of 60 = [2/3] × 60 = 40

A-type in 2022 = 60 + 40 =100

Half of A-type by X in 2019 = [1/2] × 180=90

Total ore by Y in 2022 = 100 + 90 = 190
Total ore by X in 2016 = 60 (A) + 90 (B) = 150

Difference = 190 - 150 = 40

Common Calculation

In 2016 Ore extraction by X = 150 kg

A type ore extraction by X = 150 × [40 /100] = 60 kg

B type ore extraction by X = 150 – 60 = 90 kg

Ore extraction by Y = 90 kg

A type ore extraction by Y = 90 - 30 = 60 kg

B type ore extraction by Y = 30 kg

Similarly, we can calculate the others data also.

Calculation

B-type ore by Company X in 2017 and 2019:

=90 + 60 = 150

A-type ore by Company X in 2016 = 60
A-type ore by Company Y in 2018 = 45

Sum = 60 + 45 = 105

Difference = 150 - 105 = 45

Given:

Turnover of company D = 9 lakhs

Profit of company C = 1 lakhs

Formula used:

Profit % = (Profit / CP) × 100

Calculation:

Required percentage = (1/9) × 100

⇒ 11.11 %

Hence, the correct answer is "11.11%".

Percentage of females in factory A and C together (above 40 years) = 60%

Percentage of males in factory A and C together (above 40 years) = 40%

Number of males in factory A and C together (above 40 years) = 40/100 × (50 + 110) = 64

Percentage of females in factory B and D together (above 40 years) = 50%

Percentage of males in factory B and D together (above 40 years) = 50%

Number of males in factory B and D together (above 40 years) = 50/100 × (70 + 120) = 95

∴ required ratio = 64 : 95

Total number of workers in all the factories = 200 + 400 + 340 + 320 = 1260

Total number of workers above 40 years of age = 50 + 70 + 110 + 120 = 350

∴ total number of workers in all the factories whose age is below 40 years = 1260 – 350 = 910

Total number of workers above 40 years in all the factories = 50 + 70 + 110 + 120 = 350

Number of females above 40 years in all the factories = 20% of 350 = 70

∴ required average = 70/4 = 17.5

Given:

Profit of company B = 6 lakhs

Investment of company B = 2 lakhs

Formula used:

Profit % = (Profit / CP) × 100

Calculation:

Required Profit % = (6 / 2) × 100

⇒ 3 × 100

⇒ 300%

Hence, the correct answer is "300%".

Given:

Formula used:

Average = Sum of observations/Number of observations.

Calculation:

Average number = (2200 + 1800 + 2500 + 2700 + 2900 + 3200)/6

⇒ 15300/6 = 2550

∴ The average number of students appeared for a exam per day is 2550.

Number of workers in factory D = 320

Number of workers in factory E = 320 + 20% of 320 = 384

Ratio of the number of males and females in factory E = 7 : 5

∴ required number of females = 5/12 × 384 = 160

Percentage of females in factory A and C together = 40%

Number of females in factory A and C together = 40% of (200 + 340) = 216

Percentage of males in factory B = 20%

Percentage of females in factory B = 100 – 20 = 80%

Number of females in factory B = 80% of 400 = 320

∴ Required number = 216 + 320 = 536

Number of males in factory C (above 40 years) = 30

Number of females in factory C (above 40 years) = 110 – 30 = 80

Number of males in factory A (above 40 years) = 30

Number of females in factory A (above 40 years) = 50 – 30 = 20

∴ required percentage = [(80 – 20) / 20 ] × 100 = 300%

Given:

The number of employees working in five different sectors and the respective ratio of male and female employees are given.

Calculations:

Number of employees in Q sector = 700

The number of male employees and female employees in Q sector be 5x and 9x

Total employees = (5x + 9x) = 14x

Required number of male employees in Q sector = \(\dfrac{5x}{14x}\) × 700

⇒ 5 × 50 = 250

∴ The answer is 250
