Solution:

1).Number of Professors in City Y = 10000 × 28 / 100 = 2800
Number of total professionals in City Z = 10000 × 100 / 80 = 12500
Number of Professors in City Z = 12500 × 25 / 100 = 2500
Required ratio = 2500: 2800 = 25: 28

2).Number of Dentists in City Z = 20000 × 6 / 100 = 1200
Number of total professionals in City Y
= 20000 × 5 / 4 = 25000
Number of Dentists in City Y
= 25000 × 12 / 100 = 3000
Required difference = 3000 – 1200 = 1800
3).Required % = 22 / 10 × 100 = 220%
4).Number of Accountants in City Z = 1600
Total number of professionals in City Z
= 1600 × 100 / 16 = 10000
Number of Police = 10000 × 26 / 100 = 2600
Number of Surveyors = 10000 × 22 / 100 = 2200
Required difference = (2600 – 2200) = 400
5).  Number of Dentists in City Y = 120
Total professionals in City Y
= 120 × 100 / 12 = 1000
Number of Accountants in City Z = 240
Total professionals in City Z = 240 × 100 / 16 = 1500
Required ratio = 1000: 1500 = 2: 3
6).Average price of Tomato in July
= 1 / 4 × (16 + 24 + 32 + 40) = `28 per kg
Average price of Tomato in August
= 1 / 4 × (16 + 32 + 48 + 56) = `38 per kg
Average price of Tomato in September
= 1 / 4 × (8 + 24 + 40 + 56) = `32 per kg
Average price of Tomato in October
= 1 / 4 × (8 + 16 + 48 + 56) = `32 per kg
Average price of Tomato in November
= 1 / 4 × (24 + 32 + 48 + 56) = `40 per kg
Average price of Tomato in December
= 1 / 4 × (32 + 40 + 48 + 56) = `44 per kg
In December the average price of Tomato per kg is the maximum and in July the average price of Tomato is the minimum.
7).Average price of Tomato in Mumbai
= 1 / 6 × (40 + 56 + 56 + 48 + 56 + 40)
= `49.33 kg
Average price of Tomato in Pune
= 1 / 6 × (32 + 16 + 24 + 16 + 24 + 56)
= `28 per kg
Average price of Tomato in Nagpur
= 1 / 6 × (16 + 32 + 8 + 56 + 48 + 48)
= `34.66 per kg
Average rate of Tomato in Thane
= 1 / 6 × (24 + 48 + 40 + 8 + 32 + 32)
= `30.66 per kg
Thus the maximum average price is in Mumbai.
8).Total sale of Tomato in October
= 500 × 15 / 100 = 75 tonnes
Total sale of Tomato in November = 500 × 12 / 100 = 60 tonnes
Total income in a month = (average rate that month in all cities × total quantity)
Total income in October = 32 × 75 × 1000 = `2400000
Total income in November = 40 × 60 × 1000 = `2400 000
Required difference = 2400000 – 2400000 = 0
9).Total sale of Tomato in July = 500 × 25 / 100 = 125 tonnes
Total sales in Pune in July = 125 × 35 / 100 = 43.75 tonnes
Its total cost = 43.75 × 1000 × 32 = `1400 000
