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
Let us assume the car which is 40% more popular than black is a and total number of car is P.
According to question,
(P x a/100 ) - (P x 5/100) = P x 5/100 x 40/100
P(a - 5)x1/100 = P x 5/100 x 40/100
(a - 5) = 5 x 40/100
(a - 5) = 200/100 = 2
a - 5 = 2
a = 2 + 5 = 7
40% more popular than Black cars = 7% popular Silver cars.
From above given graph ,
Given that :- % amount of money spent on housing = 15%
% amount of money spent on education = 12%
Required ratio = % amount of money spent on housing : % amount of money spent on education
Required ratio = 15 : 12 = 5 : 4.
Expenditure = Income - Profit
As per given graph in question,
Income in 2005 = 1,42,500 Rs.
Profit in 2005 = 50%
Let expenditure of Company A in 2005 = Rs. E; then
E + E x 50/ 100 =142500
? E + E x 1/2 =142500
? (2E + E)/2 =142500
? 3E =142500 x 2
? E =142500 x 2/ 3
? E = 47500 x 2
? E = Rs. 95000
As per first graph,
The number of students for course A = Total number of students x 20%
As per second graph,
The number of girls for course A = Total number of girls x 30%
Number of boys in course 'A' = The number of students for course A - The number of girls for course A
Number of boys in course 'A' = (1200 x 20/100 ) - ( 800 x 30/100 ) = 240 - 240 = 0
Number of boys in course 'C' = (1200 x 5/100 ) - (800 x 2/100) = 60 - 16 = 44
Number of boys in course 'E' = (1200 x 12/100 ) - 800 x 14/100 ) = 144 - 112 = 32
Number of boys in course 'F' = (1200 x 13/100 ) - ( 800 x 14/100 ) = 156 - 112 = 44
Hence, in course 'A' number of boys is minimum which is Zero.

Total marks obtained by Tanya in all the subjects
= 150 x 60 /100 + 84 + 50 x 80/100 + 150 x 65/100 + 125 x 50/100 + 50 x 76/100
= 90 + 84 + 40 + 97.5 + 62.5 + 38 = 412
