1). Average population
= (150000 + 170000 + 180000 + 215000 + 230000 + 240000)/6
= 1185000/6
= 197500

2). Required % = 99000 × 100/1027000
= 9.64%
= 10%

3). Required rise % = (110000 – 89000)/89000 × 100
= 23.59%
= 24%

4). Average population
= (142000 + 240000 + 93000 + 180000 + 130000 + 160000)/6
= 945000/6
= 157500

5). For China% rise = (155000 – 148000)/148000 × 100 = 4.73%
For Japan% rise = (270000 – 250000)/250000 × 100% = 8%
For Nepal% rise = (105000 – 99000)/99000 × 100% = 6.06%
For Australia% rise = (230000 – 215000)/215000 × 100% = 6.98%
For Bangladesh% rise = (145000 – 140000)/140000 × 100% = 3.57%
For India% rise = (190000 – 175000)/175000 × 100% = 8.57%
State for highest % rise = India.

6). Required Ratio
= (25 + 30) : (5 + 20)
= 55 : 25
= 11 : 5

7). Required Percentage =
= {(15 + 10 + 15) × 1000} / 455030 × 100
= {(40 × 1000)/455030} × 100
= 8.79
= 9% Approximately

8). Required total number of students
= (5 + 35 + 15 + 15 + 20 + 5) × 1000
= 95 × 1000 = 95000

9).  In 2016
Total number of girls = (20 + 20 + 5) × 38/100 × 1000
= (45 × 38 × 1000) / 100
= 17100
Total number of boys = 45000 – 17100 = 27900
Total number of boys who opted for Stenographer
= 27900 × 5/45
= 3100

10). Required percentage
= {(15000 + 30000) / (5000 + 35000 + 15000 + 25000 + 30000 + 30000)} × 100
= 45000/140000 × 100
= 32.14
= 32% Approximately
