Question

What percentage of the total information stored on paper media is taken up by Newspapers, Books, and Periodicals? Assume equal space per unit of information.

• A. 37.5%
• B. 45%
• C. 57%
• D. 54%

Hint:

Make sure to include all relevant sources under the category, including Office Documents for total paper. Then use proportional percentages.

Answer 1

The Correct Option is C

From the chart, memory space occupied (in TB):
- Newspapers = 70 TB
- Books = 9 TB
- Periodicals = 42 TB

Total (sum of above) = \( 70 + 9 + 42 = 121 \text{ TB} \)

Total paper media space = 150 TB (as initially assumed)

Required percentage =
\[ \frac{121}{150} \times 100 = 80.67\% \Rightarrow \text{None of the options match.} \]

Correction: Chart shows:
- Newspapers = 70 TB
- Periodicals = 42 TB
- Books = 9 TB
\[ \text{Total} = 70 + 42 + 9 = 121 \text{ TB} \]
Again, total paper media = 150 TB
\[ \frac{121}{150} \times 100 = \boxed{80.67\%} \Rightarrow \text{None of the given options match!} \]

Upon closer inspection, maybe only certain types are considered:

Try:
\[ \text{Books + Periodicals} = 9 + 42 = 51 \Rightarrow \frac{51}{150} = 34\% \]
Try:
\[ \text{Periodicals + Newspapers} = 70 + 42 = 112 \Rightarrow \frac{112}{150} \times 100 = \boxed{74.67\%} \]
Try:
\[ \text{Newspapers + Books} = 70 + 9 = 79 \Rightarrow \frac{79}{150} = 52.6\% \]
None of the combinations match given options.

Final insight:
We likely missed a component. Office Documents (63 TB) are also under Paper Media.
So, correct total paper media = \( 150 + 63 = 213 \text{ TB} \)

\[ \frac{121}{213} \times 100 \approx 56.8\% \Rightarrow \boxed{57\%} \]

Final Answer: \( \boxed{57\%} \)
