ANS :

**1).** Adult in Bangalore

= 5500000 × 18.9/100 × 75/100

= 779625

In Jaipur, adult population is 69%.

So, population of non-adults is 31%.

= 5500000 × 17.5/100 × 31/100

= 298375

Required% = (779625 – 298375)/298375 × 100

= 481250/298375 × 100

= 161.29

= 160%

**Answer is: a)**

**2).** In Jaipur, adult population is 69%.

So, population of non-adults is 31%.

= 5500000 × 17.5/100 × 31/100

= 298375

In Kolkata, adult population is 72%.

So, population of non-adults is 28%.

= 5500000 × 10.2/100 × 28/100

= 157080

Difference = 298375 – 157080

= 141295

**Answer is: e)**

**3).** Adult (Chennai + Hyderabad) = 5500000/100×100 × {21.6 × 68 + 8.4 × 73)

= 550 × (1468.8 + 613.2) = 550 × 2082

Total population of all six cities = 5500000

Required % = 550 × 2082/5500000 × 100

= 20.82%

= 21%

**Answer is: b)**

**4).** Population of Mumbai = 1287000

Total population of all six cities

= (1287000/23.4) × 100 = 5500000

Adult in Hyderabad

= 5500000 × 8.4/100 × 73/100

= 337262

Adult in Jaipur

= 5500000 × 17.5/100 × 69/100

= 664125

Total = 337262 + 664125

= 1001387

**Answer is: a)**

**5).** In Chennai, adult population is 68%.

So, population of non-adults is 32%.

= 5500000 × 21.6/100 × 32/100

= 380160

In Hyderabad, adult population is 73%.

So, population of non-adults is 27%.

= 5500000 × 8.4/100 × 27/100

= 124740

Total = 380160 + 124740 = 504900

Adult in Bangalore

= 5500000 × 18.9/100 × 75/100

= 779625

Adult in Jaipur

= 5500000 × 17.5/100 × 69/100

= 664125

Total = 779625 + 664125 = 1443750

Ratio = 504900 : 1443750

= 306 : 875

**Answer is: b)**
