a) 18.95

b) 16.45

c) 13.15

d) 10.25

Solutions for CAT level Data Interpretation questions:

The maximum percentage increase in price of logs happened in the year 1991 (compared to 1990) and equaled 18/15 – 1 = 20%
The maximum percentage increase in price of plywood happened in the year 1992 (compared to 1991) and equaled 6/4 – 1 = 50%
The maximum percentage increase in price of sawtimber happened in the year 1993 (compared to 1992) and equaled 20/15 – 1 = 33.33%
Hence, the correct answer is 50%

In both imports and exports, India did the least amount of trade in 1997-98 with K (both equal to 1%).
Hence, India had the lowest total trade with K in the year 1997-98.
The amount of Indian exports equals 1%*33979 = 340 millions

After an increase by 33%, the difference in the prices of one tonne of saw timber and one cubic metre of logs is given below according to the respective years.

The difference in 1987 is 15 – 10*133.33% = 1.67
The difference in 1988 is 16 – 10*133.33% = 2.67
The difference in 1989 is 17.5 – 12*133.33% = 1.5
The difference in 1990 is 15 – 10*133.33% = 1.67
The difference in 1991 is 17.5 – 12.5*133.33% = 0.833
The difference in 1992 is 18 – 15*133.33% = -2
The difference in 1993 is 20 – 20*133.33% = -6.67
Hence, the difference is least in the year 1991.

From the above diagram, we can say that difference is highest in 1992.

In 1993, price of logs = Rs. 20 per cubic metre.Price of plywood = 7/1.33 = Rs 5.26 per cubic metre. Price of saw timber = 19/1.33 = Rs 14.28 per cubic metre.
We know that the sales volume of plywood, saw timber and logs are in the ratio 4 : 3 : 3.
Thus, the average realization must be the weighted avg of these three-
$$\frac{(4\times 5.26)+(3 \times 14.28)+(3 \times 20)}{4+3+3}$$
=12.4
= Rs. 13 (Approximately)

$$\frac{(4\times 5.26 \times 1.05)+(3 \times 14.28 \times 1.01)+(3 \times 20 \times 1.1)}{4+3+3} \approx 13.15$$
