Question 1

The average production of 1990 and 1991 was exactly equal to the average production of which of the following pairs of years?

Accepted Answer

As per given graph in question, The average production of 1990 and 1991 = (40 + 60)/2 = 100/2 = 50 The average production of 1991 = 60 Solve one by one option. (A) The average production of 1991 and 1992 = (60 + 45)/2 = 105/2 = 52.5 (B) The average production of 1992 and 1994 = (45 + 50)/2 = 95/2 = 47.5 (C) The average production of 1993 and 1994 = (65 + 50)/2 = 115/2 = 57.5 (D) The average production of 1994 and 1995 = (50 + 75)/2 = 125/2 = 62.5 All the given option doesn't have average production of 50. So answer will be none of these.

Question 2

What was the difference in the production of food-grains between 1991 and 1994?

Accepted Answer

Difference in the production of food-grains between 1991 and 1994 = Production of food-grains in 1991 - Production of food-grains in 1994 Put the value by seeing the graph Difference in the production of food-grains between 1991 and 1994 = ( 60 − 50 ) x 1000 = 10 x 1000 = 10,000

Question 3

In which of the following years was the percentage increase in production from the previous year the maximum among the given years?

Accepted Answer

Check given option one by one. Option (A), Percentage increase in production in 1991 = {(Production in 1991 - Production in 1990)} x 100 % / Production in 1990 Percentage increase in production in 1991 = {( 60 - 40 )} x 100 % / 40 Percentage increase in production in 1991 = 20 x 100 % / 40 Percentage increase in production in 1991 = 100 % / 2 = 50 % Option (B) Percentage increase in production in 1993 = {( Production in 1993 - Production in 1992 )} x 100 % / Production in 1992 Percentage increase in production in 1993 = {( 65 - 45 )} x 100 % / 45 Percentage increase in production in 1993 = 20 x 100 % / 45 Percentage increase in production in 1993 = 4 x 100 % / 9 = 400/9 = 44.44 % Option (C) Percentage increase in production in 1995 = {( Production in 1995 - Production in 1994 )} x 100 % / Production in 1994 Percentage increase in production in 1995 = {( 75 - 50 )} x 100 % / 50 Percentage increase in production in 1995 = 25 x 100 % / 50 Percentage increase in production in 1995 = 100 % / 2 =50 % Option (D) Percentage increase in production in 1990 = {( Production in 1990 - Production in 1989 )} x 100 % / Production in 1989 Percentage increase in production in 1990 = {( 40 - 25)} x 100 % / 25 Percentage increase in production in 1990 = 15 x 100 % / 25 Percentage increase in production in 1990 = 15 x 4 % = 60 %

Question 4

What was the percentage drop in the production of food-grains from 1991 to 1992?

Accepted Answer

Question 5

In how many of the given years was the production of foodgrains more than average production of the given years?

Accepted Answer

Question 6

What is the approximate average production of roses (in thousands) across all the states?

Accepted Answer

Question 7

Which of the following State(s) contribute(s) less than 10 % in the total rose production?

Accepted Answer

Total rose production = ( 15000 + 12500 + 12450 + 20000 + 12400 + 22500 + 22400 + 25000 ) = 142250 % Rose Production increase in State = Rose production in state x 100 / Rose production in All state % Rose Production increase in Gujrat = Rose production in Gujrat x 100 / Rose production in All state % Rose Production increase in Gujrat = 15000 x 100 / 142250 % Rose Production increase in Gujrat = 1500 x 100 / 14225 % Rose Production increase in Gujrat = 300 x 100 / 285 % Rose Production increase in Gujrat = 60 x 100 / 57 % Rose Production increase in Gujrat = 6000 / 57 = 10.54 % Similarly Calculate the % Rose Production increase in all states one by one and compare them. Percentage production of rose in the States (the lowest four states)

Question 8

If total percentage contribution of the States having production of roses below twenty thousand is considered, which of the following statements is true?

Accepted Answer

It is 36.8% approximately.

Question 9

By what percentage rose production of other States is more than that of the Maharashtra?

Accepted Answer

Question 10

Approximately what percentage of the total rose production is shared by the other States?

Accepted Answer

Question 11

What was the approximate % drop in sale of Pep-up in 1990 over its sale in 1989?

Accepted Answer

Question 12

In the year 1990, what was the difference between the number of 'Pep-up' and 'Cool-sip' bottles sold?

Accepted Answer

Difference in Required number = Number of Pep-up drink sold in 1990 - Number of Cool-sip drink sold in 1990. Difference in Required number = 30 million − 20 million = 10 million. Difference in Required number = 10 million = 10 x 1000000 ( Since 1 million = 1000000 ) Difference in Required number = 10 million = 10000000

Question 13

In the case of Cool-sip drink, what was the approximate % increase in sale in 1992 over its sale in 1991?

Accepted Answer

Question 14

In the case of which soft drink was the average annual sale maximum in the given period?

Accepted Answer

Question 15

In which year was the sale of 'Pep-up' the maximum?

Accepted Answer

By comparing the Sale of Pep-up for all years and we found that the Sale of Pep-up was the maximum in the year 1989.

Question 16

What is the ratio of total imports to total exports for all the given years together?

Accepted Answer

Question 17

The total exports in the years 1995, 1996 and 1999 together are what % of the total import during the same period? (up to two decimal places)

Accepted Answer

Question 18

Which of the following pairs of years and the % increase in the export over the previous year is correctly matched?

Accepted Answer

Question 19

During which year the percentage rise/fall in imports from the previous year is the lowest?

Accepted Answer

As per given graph we can see the difference is very less in 1998. Obvious from the chart its 1998 .

Question 20

In which of the following pairs of years the total import is equal to total export in the same pair of years?

Accepted Answer

Obvious from the chart , we can say that 1998–1999 year has the same import and export.
