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

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%
