Given:
The number of copies of Indian Express sold in Urban area = 1000
The number of copies of Indian Express sold in Rural area = 500
Calculations:
⇒ Required percentage = (1000 – 500)/500 × 100
⇒ Required percentage = (500)/500 × 100
⇒ Required percentage = 100%
∴ The number of copies of Indian Express sold in Urban areas is 100% more than the number of copies of Indian Express sold in Rural areas.

The ratio of male and female in every Rural area = 3 : 2
Calculation:
Number of males who purchased Business Standard from rural areas = 1500 × 3/5 = 900
Number of males who purchased Dainik Bhaskar from rural areas = 4500 × 3/5 = 2700
Required number of male = 900 + 2700 = 3600
∴ The number of males who purchased Business Standard and Dainik Bhaskar from rural areas is 3600.

Given:
The ratio of male and female in every Urban area = 2 : 3
Calculation:
Number of female who purchased Times of India from urban areas = 2000 × 3/5 = 1200
Number of female who purchased Patrika from urban areas = 3000 × 3/5 = 1800
Required number of female = 1800 + 1200 = 3000
∴ The number of female who purchased Times of India and Patrika from urban areas is 3000.
8. Below mentioned table shows usage of Netflix, amazon prime and sony liv over a span of 150 hours in three families. Answer the questions from data mentioned below:
| Netflix | Amazon Prime | Sony Iiv | |
| Family 1 | 10% | 20% | 25% |
| Family 2 | 45% | 10% | 25% |
| Family 3 | 30% | 15% | 20% |
-
25 hours
-
28 hours
-
37.5 hours
-
53 hours
Calculation:
Total number of hours watched on Netflix by all three families = (0.10 × 150) + (0.45 × 150) + (0.30 × 150)
⇒ (0.10 × 150) + (0.45 × 150) + (0.30 × 150) = 0.85 × 150
⇒ 0.85 × 150 = 127.5 ….(1)
Total number of hours watched on Sony Liv by all three families = (0.25 × 150) + (0.25 × 150) + (0.20 × 150)
⇒ (0.25 × 150) + (0.25 × 150) + (0.20 × 150) = 0.70 × 150 ….(2)
⇒ 0.70 × 150 = 105
Difference = (1) – (2)
⇒ 127.5 – 105
∴ Required difference = 22.5 hours
Hint
Number of hours watched by all families is from 150 hence, add the percentages and then obtain total hours used to reduce the calculation time.
9. Below mentioned table shows usage of Netflix, amazon prime and sony liv over a span of 150 hours in three families. Answer the questions from data mentioned below:
| Netflix | Amazon Prime | Sony Iiv | |
| Family 1 | 10% | 20% | 25% |
| Family 2 | 45% | 10% | 25% |
| Family 3 | 30% | 15% | 20% |
Find ratio between total hours watched by family 1 on Netflix and Amazon prime and by family 2 on Amazon prime and sony liv.
-
3 : 4
-
5 : 4
-
7 : 6
-
4 : 5
Calculation:
Number of hours watched on Netflix by family 1 = 0.10 × 150
⇒ 0.10 × 150 = 15 ….(1)
Number of hours watched on Amazon prime by family 1 = 0.20 × 150
⇒ 0.20 × 150 = 30 ….(2)
Number of hours watched on Amazon Prime by family 2 = 0.10 × 150
⇒ 0.10 × 150 = 15 ….(3)
Number of hours watched on sony liv by family 2 = 0.25 × 150
⇒ 0.25 × 150 = 37.5 ….(4)
Now, (1) + (2) : (3) + (4)
⇒ (15 + 30) : (15 + 37.5)
⇒ 45 : 52.5
⇒ 9 : 10.5
∴ Required ratio is 6 : 7
Total number of hours watched on Netflix and Amazon prime by family 1 = (0.30) × 150
⇒ 0.30 × 150 = 45 ….(1)
Total number of hours watched on Amazon prime and Sony liv by family 2 = (0.35) × 150
⇒ 0.35 × 150 = 52.5 ….(2)
Now, (1) : (2)
⇒ 45 : 52.5
∴ Required ratio is 6 : 7
10. Below mentioned table shows usage of Netflix, amazon prime and sony liv over a span of 150 hours in three families. Answer the questions from data mentioned below:
| Netflix | Amazon Prime | Sony Iiv | |
| Family 1 | 10% | 20% | 25% |
| Family 2 | 45% | 10% | 25% |

Find total number of hours watched on Amazon prime and sony liv by family 2 and family 3
-
110
-
115
-
120
-
125
Calculation:
Number of hours watched on amazon prime by family 2 = 0.10 × 150
⇒ 0.10 × 150 = 15 ….(1)
Number of hours watched on sony liv by family 2 = 0.25 × 150
⇒ 0.25 × 150 = 37.5 ….(2)
Number of hours watched on amazon prime by family 3 = 0.15 × 150
⇒ 0.15 × 150 = 22.5 ….(3)
Number of hours watched on sony liv by family 3 = 0.20 × 150
⇒ 0.20 × 150 = 30 ….(4)
Required answer = (1) + (2) + (3) + (4)
⇒ 15 + 37.5 + 22.5 + 30 = 105
∴ Required answer is 105 hours
Number of hours watched on amazon prime and sony liv by family 2 = (0.10 + 0.25) × 150
⇒ Number of hours watched on amazon prime and sony liv by family 2 = 52.5 ….(1)
Number of hours watched on amazon prime and sony liv by family 3 = (0.15 + 0.20) × 150
⇒ Number of hours watched on amazon prime and sony liv by family 3 = 52.5 ….(2)
Total number of hours asked = (1) + (2)
⇒ 52.5 + 52.5
⇒ required answer = 105
∴ Required answer is 105 hours
