In 1997?98, the expenditure of Company X was $ 40 billion. What was its income in that year?

Average production of A = 50
Average production of B = 54.17
Average production of C = 50
Difference of production = 54.17 ? 50 = 4.17.

As per above given table , we can see that
Q State has the highest grain production .
Hence correct option will be B .

Given : - According to question ,
Total number of students in school = 400 students
Ratio of boys and girls in school = 3 : 5
Let us assume the ration is P.
Number of boys = 3P
Number of girls = 5P
3P + 5P = 400
8P = 400
P = 50
Number of boys = 3P = 3 x 50 =150
Number of girls = 5P = 5 x 50 = 250
% of the students speak only Hindi = 24%
number of boys speak only Hindi = 18
According to question ,
The total number of girls speaking Hindi
= 24% × Total number of students - number of boys speak only Hindi
= 24% × 400 - 18
= 96 - 18 = 78

Total expenditure in 6 years = ( expenditure in 1993 + expenditure in 1994 + expenditure in 1995 + expenditure in 1996 + expenditure in 1997 + expenditure in 1998 ).
As we can see in the given graph that,
Income in 1993 = 120
Profit = 7.5 %
Then Expenditure in 1993 = 120 X 100 / 107.5
Similarly
Expenditure in 1994 = 160 X 100 / 115
Expenditure in 1995 = 130 X 100 / 122.5
Expenditure in 1996 = 170 X 100 / 117.5
Expenditure in 1997 = 190 X 100 / 120
Expenditure in 1998 = 150 X 100 / 127.5
Total Expenditure in 6 years = ( 120 X 100 / 107.5 ) + ( 160 X 100 / 115 ) + ( 130 X 100/122.5 ) + ( 170 X 100 / 117.5 ) + ( 190 X 110 / 120 ) + ( 150 X 100/127.5 )
Total Expenditure in 6 years = 111.6 2 +139.13 + 106.16 + 144.68 + 158.33 + 117.64
Total Expenditure in 6 years = 777.56
Average expenditure per years = 777.56 / 6 = 12 .59 ? $ 130 Million

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

Increase in the price of crude oil in the given month with respect to the corresponding previous months:
In March ? (3980 - 3210) x 100 /3210 ? 24%
In April ? (4800 - 3980) x 100/3980 = 20.6%
In May ? (4940 - 4800)/4800 x 100 ? 3%
In June ? (4970 - 4940)/4970 x 100 = 0.6%
In July ? (5730 - 4970 )x100 /4970 = 15.3%
In August ? (6250 - 5730)x 100/5730 = 9.07%
In September ? (7020 - 6250)x 100/6250 = 12.32%
It is shown that in the months of July and September, increase in the crude oil price was more than 10% but less than 20% over the earlier month.

Here as per graph food expenditure , 40% = Rs. 750 per month
? 10% = 10 x 750/40 = Rs. 187.50 per month
As per graph 10% is the expenditure on education.
? Annual expenditure (12 months) of the family on education = 187.50 x 12 = Rs. 2250
