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

Correct 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

What is the difference between average demand and average production of computers of the five months taken together?

1. 540
1. 260

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 = 5
Average demand = 8100 = 1620
5

Total production of computers of the five months = 1000 + 1300 + 500 + 2200 + 1800 = 6800
Number of months = 5
Average 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 = 5
Average demand = 8100 = 1620
5

Total production of computers of the five months = 1000 + 1300 + 500 + 2200 + 1800 = 6800
Number of months = 5
Average production = 6800 = 1360
5

Required difference = Average demand - Average production
∴ Required difference = 1620 – 1360 = 260

The production of computers in April is approximately how many times that of production in January?

1. 2.2
1. 1.8
1. 1.4
1. 2.6

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

Required answer = 2200 = 2.2
1000

What percent of the demand of computers for the month of March is the demand of computers for the month of February?

1. 5%
1. 10%
1. 7.5%
1. 15%

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 = 100
Required 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 = 100
Required 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?

1. January
1. April
1. May
1. February

View Hint View Answer Discuss in Forum

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 .
