What is the maximum percentage increase in price per cubic metre or per tonne over the previous year?
Show Hint
To find the maximum percentage increase, compute year-over-year changes for all categories and compare the values.

The Correct Option is C
Solution and Explanation
We examine the prices of plywood, saw timber, and logs from the chart for each year (1987 to 1993), looking for the maximum percentage increase from one year to the next.
From the graph:
- Logs:
- 1989 to 1990: increase from approx. Rs. 4 to Rs. 6
\[
\frac{6 - 4}{4} \times 100 = 50%
\]
- Plywood:
- 1990 to 1991: increase from approx. Rs. 9 to Rs. 12
\[
\frac{12 - 9}{9} \times 100 = 33.33%
\]
- Saw timber:
- 1990 to 1991: increase from approx. Rs. 15 to Rs. 17.5
\[
\frac{17.5 - 15}{15} \times 100 \approx 16.67%
\]
Hence, the maximum percentage increase is for logs from 1989 to 1990, which is:
\[
\boxed{50%}
\]

Question: 2
Which product shows the maximum percentage increase in price over the period?
Which product shows the maximum percentage increase in price over the period?
Show Hint
Compare the prices from the beginning to the end of the period for each product to find total percentage change.

- Saw timber
- Plywood
- Logs

Show Solution

The Correct Option is B
Solution and Explanation
From the graph, observe the prices from 1987 to 1993. Plywood shows a noticeable increase from around Rs. 15 to Rs. 20.
Percentage increase =
\[
\frac{20 - 15}{15} \times 100 = 33.33%
\]
Compare with saw timber and logs: Their fluctuations are less over the period. Thus, plywood shows the highest percentage increase over the entire period.

Question: 3
If 1 m$^3$ = 750 kg for saw timber, find in which year was the difference in prices of saw timber and logs the least?
If 1 m$^3$ = 750 kg for saw timber, find in which year was the difference in prices of saw timber and logs the least?
Show Hint
To minimize price difference, look for years where the two price curves are closest.

- 1989
- 1990
- 1991
- 1992
Show Solution

The Correct Option is B
Solution and Explanation
From the graph, observe saw timber and log prices across years.
In 1990, the prices of both saw timber and logs are the closest together, so the difference in prices is the least.
This is visually evident from the chart where the two lines nearly converge.

Question: 4
If one cubic metre = 700 kg for plywood and 800 kg for saw timber, find in which year was the difference in the prices of plywood and saw timber (per cubic metre) the maximum?
If one cubic metre = 700 kg for plywood and 800 kg for saw timber, find in which year was the difference in the prices of plywood and saw timber (per cubic metre) the maximum?
Show Hint
Use unit conversion before comparing values across products.

The Correct Option is D
Solution and Explanation
Convert the given prices to per cubic metre using conversion factors.
Check each year:
- In 1992:
Plywood: Rs. 19 (approx)
Saw timber: Rs. 12 (approx)
Plywood per m$^3$ = Rs. 19 for 700 kg
Saw timber per m$^3$ = Rs. 12 for 800 kg
The gap is maximum in 1992 when comparing these scaled values.

Question: 5
If the volume sales of plywood, saw timber and logs were 40%, 30% and 30% respectively, then what was the average realisation in 1993 per cubic metre of sales?
If the volume sales of plywood, saw timber and logs were 40%, 30% and 30% respectively, then what was the average realisation in 1993 per cubic metre of sales?
Show Hint
Use weighted average: multiply each price by its sales proportion and sum.

The Correct Option is D
Solution and Explanation
Prices in 1993 (approx from chart):
- Plywood: 20
- Saw timber: 14
- Logs: 6
Average Realisation:
\[
0.4 \times 20 + 0.3 \times 14 + 0.3 \times 6 = 8 + 4.2 + 1.8 = \boxed{14}
\]
However, the closest option is (D) 13, which appears to be a misprint. Based on calculation, correct average is 14.

Question: 6
If, in 1994, prices increased by 5%, 1% and 10% while the volume sales break-up was 40%, 30% and 30% for plywood, saw timber and logs respectively, then what was the average realisation?
If, in 1994, prices increased by 5%, 1% and 10% while the volume sales break-up was 40%, 30% and 30% for plywood, saw timber and logs respectively, then what was the average realisation?
Show Hint
Always apply percentage increases to old values first, then compute weighted average.

- 18.95
- 16.45
- 13.15
- 10.25
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
New prices in 1994 after increase:
- Plywood: 20 + 5% = 21
- Saw timber: 14 + 1% = 14.14
- Logs: 6 + 10% = 6.6
Weighted average:
\[
0.4 \times 21 + 0.3 \times 14.14 + 0.3 \times 6.6 = 8.4 + 4.242 + 1.98 = \boxed{14.622}
\]
Closest option is 13.15 (though actual value is approx 14.62, indicating possible typo or difference in assumed base price).
