From the given bar diagram , we see
Number of the month having more demand than production i.e.( January , March and May ) = 3
Number of the month having more production than demand i.e. ( February , April ) = 2
Required ratio = Number of the month having more demand than production : Number of the month having more production than demandCorrect Option: B
From the given bar diagram , we see
Number of the month having more demand than production i.e.( January , March and May ) = 3
Number of the month having more production than demand i.e. ( February , April ) = 2
Required ratio = Number of the month having more demand than production : Number of the month having more production than demand
∴ Required ratio = 3 : 2

As per the given bar graph , we have
Total demand of computers of the five months = 2500 + 100 + 2000 + 700 + 2800 = 8100
Number of months = 5Average demand = 8100 = 1620 5
Total production of computers of the five months = 1000 + 1300 + 500 + 2200 + 1800 = 6800
Number of months = 5Average production = 6800 = 1360 5
Correct Option: D
As per the given bar graph , we have
Total demand of computers of the five months = 2500 + 100 + 2000 + 700 + 2800 = 8100
Number of months = 5Average demand = 8100 = 1620 5
Total production of computers of the five months = 1000 + 1300 + 500 + 2200 + 1800 = 6800
Number of months = 5Average production = 6800 = 1360 5
Required difference = Average demand - Average production
∴ Required difference = 1620 – 1360 = 260

From the given bar diagram , we see
The production of computers in April = 2200
The production of computers in January = 1000Required answer = The production of computers in April The production of computers in January
Correct Option: A
From the given bar diagram , we see
The production of computers in April = 2200
The production of computers in January = 1000Required answer = The production of computers in April The production of computers in January Required answer = 2200 = 2.2 1000

On the basis of given graph in question ,
The demand of computers for the month of March = 2000
The demand of computers for the month of February = 100Required percentage = The demand of computers for the month of February × 100 The demand of computers for the month of March
Correct Option: A
On the basis of given graph in question ,
The demand of computers for the month of March = 2000
The demand of computers for the month of February = 100Required percentage = The demand of computers for the month of February × 100 The demand of computers for the month of March Required percentage = 100 × 100 = 5% 2000
- Which month has least demand of computers relative to production?

According to given bar graph , we have
January ⇒ 2500 × 100 = 250% 1000 Febraury ⇒ 100 × 100 = 100 % 1300 13
Correct Option: D
According to given bar graph , we have
January ⇒ 2500 × 100 = 250% 1000 Febraury ⇒ 100 × 100 = 100 % 1300 13 April ⇒ 700 × 100 ≈ 32% 2200
Therefore , February month has least demand of computers relative to production .
