Step 1: Determine the profit percentage in 1998 from the graph.
Looking at the line graph, the profit percentage in 1998 is 65\%.
Step 2: Understand the relationship between Income, Expenditure, and Profit Percentage.
The profit percentage is calculated as:
$$\text{Profit Percentage} = \frac{\text{Income} - \text{Expenditure}}{\text{Expenditure}} \times 100$$
Step 3: Substitute the given values and solve for Expenditure.
We are given that the Income in 1998 was \( \rupee 264 \) crores, and the Profit Percentage was 65\%. Let the Expenditure in 1998 be \( E \) crores. Substituting these values into the formula:
$$65 = \frac{264 - E}{E} \times 100$$
Now, we need to solve this equation for \( E \):
$$\frac{65}{100} = \frac{264 - E}{E}$$
$$0.65 = \frac{264 - E}{E}$$
Multiply both sides by \( E \):
$$0.65 E = 264 - E$$
Add \( E \) to both sides:
$$0.65 E + E = 264$$
$$1.65 E = 264$$
Divide by 1.65:
$$E = \frac{264}{1.65}$$
To simplify the calculation, we can multiply the numerator and denominator by 100:
$$E = \frac{26400}{165}$$
Now, lets perform the division:
$$E = 160$$
So, the expenditure in 1998 was \( \rupee 160 \) crores.
