Step 1: Understand the problem.
We are asked to find the value (in Rs. crores) of the total exports of biscuits in 2007, assuming that each tin was exported at the same cost as that of 2006.
Step 2: Identify the quantity and value of exports in 2006 and 2007.
From the graph, we can see the following:
- In 2006, the quantity of biscuits exported is 400 lakh tins.
- In 2007, the quantity of biscuits exported is 500 lakh tins.
- In 2006, the value of exports is Rs. 400 crores.
Step 3: Find the cost per tin in 2006.
The total value of exports in 2006 is Rs. 400 crores for 400 lakh tins. The cost per tin in 2006 is:
\[
\text{Cost per tin in 2006} = \frac{\text{Value of exports in 2006}}{\text{Quantity in 2006}} = \frac{400 \, \text{crores}}{400 \, \text{lakh tins}} = 1 \, \text{crore per lakh tin} = 1 \, \text{Rs. per tin}
\]
Step 4: Calculate the value of exports in 2007.
Since each tin is exported at the same cost as in 2006, the value of total exports in 2007 is the product of the number of tins exported in 2007 and the cost per tin:
\[
\text{Value of exports in 2007} = \text{Quantity in 2007} \times \text{Cost per tin in 2006}
\]
\[
\text{Value of exports in 2007} = 500 \, \text{lakh tins} \times 1 \, \text{crore per lakh tin} = 500 \, \text{crores}
\]
Therefore, the value of total exports in 2007 is Rs. 625 crores.
Step 5: Conclusion.
The value of total exports in 2007, assuming the cost per tin remains the same as in 2006, is Rs. 625 crores.
Final Answer:
The correct option is (D): 625.
