The total imports (in Billion) made by all the three companies together: From the heights of the points we observe that the total heights of three points is the maximum either in 1995 or 1997. If you observe carefully, our clear answer is 1995, but to be sure we find actual values for the two years.
In 1995 = 70 + 80 + 85 = 235.
In 1997 = 75 + 70 + 85 = 230.
Clearly, 1995 is the desired year.
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% + 84 + 50 x 80% + 150 x 65% + 125 x 50 + 50 x 76%
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
Required ratio = number of building demolished in City T / number of buildings redeveloped in city P
Required ratio = 175 : 300 = 7 : 12
For course E,
Number of boys = ( 1200 x 12/100 ) - (800 x 14/100 ) = 144 - 112 = 32
Number of girls = 800 x 14/100 = 112
Required percentage = ( (112 - 32 )/32 ) x 100 = (80/32) x 100 = 250%
