Question

How many A4 size paper sheets will make A0 size?

• A. 3
• B. 4
• C. 16
• D. 8

Hint:

Each smaller ISO ‘A’ paper size has half the area of the previous one, maintaining the same aspect ratio (1:√2).

Answer 1

The Correct Option is C

Step 1: Understanding ISO paper sizes.
Each successive paper size (A0 to A4) is obtained by halving the previous size along the larger dimension.
Step 2: Explanation.
A0 → A1 → A2 → A3 → A4 represents 4 successive halvings. Thus, \(2^4 = 16\). Therefore, sixteen A4 sheets equal one A0 sheet in area.
Step 3: Conclusion.
Hence, 16 A4 sheets make one A0 size sheet.
