The following line graph gives the annual percent profit earned by a Company during the period 1995 - 2000.
Percent Profit Earned by a Company Over the Years.
| %Profit = | Income - Expenditure | x 100 |
| Expenditure |
1.
If the expenditures in 1996 and 1999 are equal, then the approximate ratio of the income in 1996 and 1999 respectively is?
Answer: Option
Explanation:
Let the expenditure in 1996 = x.
Also, let the incomes in 1996 and 1999 be I1 and I2 respectively.
Then, for the year 1996, we have:
| 55 = | I1 - x | x 100 |  |
55 | = | I1 | - 1 | I1 = |
155x | ... (i) |
| x | 100 | x | 100 |
| 70 = | I2 - x | x 100 | |
70 | = | I2 | - 1 | I2 = |
170x | ... (ii) |
| x | 100 | x | 100 |
From (i) and (ii), we get:
| I1 | = |
|
= | 155 |  |
0.91 | 9 : 10. |
