The following line graph gives the percent profit earned by two Companies X and Y during the period 1996 - 2001.
Percentage profit earned by Two Companies X and Y over the Given Years
%Profit = ((Income - Expenditure) / Expenditure) x 100
If the expenditure of Company Y in 1997 was Rs. 220 crores, what was its income in 1997 ?
Rs. 312 crores
Rs. 297 crores
Rs. 283 crores
Rs. 275 crores
Correct answer is B
Profit percent of Company Y in 1997 = 35.
Let the income of Company Y in 1997 be Rs. x crores.
Then, 35 = (x - 220)/220 x 100 => x = 297
Therefore Income of Company Y in 1997 = Rs. 297 crores.
The following line graph gives the percent profit earned by two Companies X and Y during the period 1996 - 2001.
Percentage profit earned by Two Companies X and Y over the Given Years
%Profit = ((Income - Expenditure) / Expenditure) x 100
7:22
14:19
15:22
27:35
Correct answer is C
Let the incomes in 2000 of Companies X and Y be 3x and 4x respectively.
And let the expenditures in 2000 of Companies X and Y be E1 and E2 respectively.
Then, for Company X we have:
65 = (3x - E1)/E1 x 100 => 65/100 = 3x/E1 - 1 => E1 = 3x x ( 100/165 ) .... (i)
For Company Y we have:
50 = (4x - E2)/E2 x 100 => 50/100 = 4x/E2 - 1 => E2 = 4x x ( 100/150 ) .... (ii)
From (i) and (ii), we get:
E1/E2 = (3x x ( 100/165 ))/(4x x ( 100/150 )) = (3 x 150)/(4 x 165) = 15/22 (Required ratio)
Study the following line graph and answer the questions based on it.
Number of Vehicles Manufactured by Two companies over the Years (Number in Thousands)
1997
1998
1999
2000
Correct answer is D
The difference between the productions of Companies X and Y in various years are:
For 1997 (139000 - 119000) = 20000.
For 1998 (120000 - 99000) = 21000.
For 1999 (141000 - 100000) = 41000.
For 2000 (128000 - 78000) = 50000.
For 2001 (120000 - 107000) = 13000.
For 2002 (159000 - 148000) = 11000.
Clearly, maximum difference was in 2000
Study the following line graph and answer the questions based on it.
Number of Vehicles Manufactured by Two companies over the Years (Number in Thousands)
119333
113666
112778
111223
Correct answer is A
Average number of vehicles manufactured by Company X
= 1/6 x (119000 + 99000 + 141000 + 78000 + 120000 + 159000)
= 119333.
