- Statements I and II together are not sufficient
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
To find the number of bricks, we need either dimensions of the wall and bricks, or total cost and cost per brick.
Step 2: Analysis of Statement I
Gives ratios and brick size, but no actual dimensions of the wall. Not sufficient.
Step 3: Analysis of Statement II
Price of 100 bricks = Rs 500 $\Rightarrow$ Price of 1 brick = Rs 5. Total cost = Rs 12,000. Number of bricks = $\frac{12,000}{5} = 2,400$. Statement II alone provides a unique answer.
Step 4: Conclusion
Correct answer is (2). Final Answer: (2)
