(b) Find the ratio of the number of males in Bihar and MP.
(c) Find the percentage of people living in Urban areas in Delhi, TN, and rural areas in UP taken together.
(d) Find the total number of females in UP And MP.
(e) Find the sum of male population from Rajasthan, female population from TN and people living in Urban areas from Delhi.
(a) What will be the percentage of Population living in Rural areas of Uttar Pradesh (UP), Delhi, Rajasthan, and Tamil Nadu (TN) taken together of the total population?
Answer:
Total Population of Uttar Pradesh (UP) = 3900 × 105 × 25/100
Ratio of people living in Rural areas to Urban areas = 5:3
Total number of people living in Rural areas in UP = 3900 × 105 × 25/100 × 5/8
= 609.3× 105
Total Population of Delhi = 3900 × 105 ×15/100
Ratio of people living in Rural areas to Urban areas = 3:7
Total number of people living in Rural areas in UP = 3900 × 105 × 15/100 × 3/10
= 175.5 × 105
Total Population of Rajasthan = 3900 × 105 ×15/100
Ratio of people living in Rural areas to Urban areas = 7:5
Total number of people living in Rural areas in UP = 3900 × 105 × 15/100 × 7/12
= 341.2 × 105
Total Population of Tamil Nadu (TN) = 3900 × 105 × 13/100
Ratio of people living in Rural areas to Urban areas = 3:2
Total number of people living in Rural areas in UP = 3900 × 105 × 13/100 × 3/5
= 304.2 × 105
Total Population living in in Rural Areas in all four states- Uttar Pradesh (UP), Delhi, Rajasthan, and Tamil Nadu (TN)
= 609.3 × 105 + 175.5 × 105 + 341.2 × 105 + 304.2 × 105
= 1430.2 × 105
Hence, the percentage of Population living in Rural areas of Uttar Pradesh (UP), Delhi, Rajasthan, and Tamil Nadu (TN) taken together of the total population
= (1430.2 × 105/3900 × 105) × 100
= 36.6%
(b) Find the ratio of the number of males in Bihar and MP.
Answer:
Total population of Bihar = 3900 × 105 ×12/100
Ratio of males to females in Bihar = 5:3
Total number of males in Bihar = 3900 × 105 ×12/100 × 5/8 = 292.5 × 105
Total population of Madhya Pradesh (MP) = 3900 × 105 × 20/100
Ratio of males to females in Bihar = 5:4
Total number of males in Bihar = 3900 × 105 × 20/100 × 5/9 = 433.3 × 105
Ratio = 292.5: 433.3 = 2925: 4333
Hence, the ratio of the number of males in Bihar and MP is 2925: 4333.
(c) Find the percentage of people living in Urban areas in Delhi, TN, and rural areas in UP taken together.
Answer:
Percentage of people living in Urban areas in Delhi = 15% × 7/10
= 10.5%
Percentage of people living in Urban areas in Tamil Nadu (TN) = 13% × 2/5
= 5.2%
Percentage of people living in rural areas in Uttar Pradesh (UP) = 25% × 5/8 = 15.6%
Total percentage of people living in Urban areas in Delhi, TN, and UP taken together is 10.5% + 5.2% + 15.6% = 31.3%
(d) Find the total number of females in UP And MP.
Answer:
Total number of females in UP = 25% × 3900 × 105 × 3/8
= 365.6 × 105
Total number of females in MP = 20% × 3900 × 105 × 4/9 = 346.6 × 105
The total number of females in UP And MP = 365.6 × 105 + 346.6 × 105
= 712.2 × 105
(e) Find the sum of male population from Rajasthan, female population from TN and people living in Urban areas from Delhi.
Answer:
Male population from Rajasthan = 3900 × 105 × 15/100 × 2/5
= 234 × 105
Female population from Tamil Nadu (TN) = 3900 × 105 × 13/100 × 2/5
= 202.8 × 105
People living in Urban area from Delhi = 3900 × 105 × 15/100 × 7/10
= 202.8 × 105
Sum = 234 × 105 + 202.8 × 105 + 202.8 × 105 = 846.3 × 105
Hence, the sum of male population from Rajasthan, female population from TN and people living in Urban areas from Delhi is 846.3 × 105.
