Data Interpretation Solutions with Answers

Answer 1: a
(100.5 + 67 + 141 + 143.9 + 65)/5 = 103.48

Answer 2: a
As we see the table we see that the performance of only year i.e. 88 is less than the year 85. Hence the percentage corresponding to 1988 should be less than 100. Thus we see that (c) cannot be the answer.
Also (b) cannot be the answer as it shows two of the two years having less than 100%. 
Between options (a) and (d), the correct answer is (a). This is because the difference between the 1985 and 1988 performance is only 2 units on 67 units. Hence percentage wise, it has to be 97% and not 68%.

Answer 3: b
The highest percentage decrease over the previous year is in year 1988 as in the table, and the performance is almost half than that of the previous year. Such a decrease is not seen in any other year, so the right answer is b

Answer 4: c
Total expenditure = 52.1+267.5+196.4+209.5 = 725.5 lakhs.
If it has to be kept within 700 lakhs, the expenditures have to reduce by 25.5 lakhs.
So the expenditure reduced each year will be (25.5/4) = 6.375 lakhs.
Hence, percentage reduce for 1989 would be = (6.375/15) × 100 = 42.5%.

Answer 5: b
Costs of material and labor
1988 = 2.1
1989 = 95+70+15+25+25 = 230
1990 = 80+45+12+18+20 = 175
1991 = 75+60+16+21+18 = 190
Therefore proportion of these expenditures till 1990 = (2.1 + 230 + 175) / (2.1 + 230 + 175 + 190) = 0.6817.
This will also be the fraction of the total length of the line.

Answer 6: b
Total material cost =(95+80+75+70+45+60+15+12+16+25+18+21) = 532
Total labour cost = (2.1+25+20+18) = 65.1
Therefore the ratio = 532 : 65.1 = 8 : 1 (approximately)

Answer 7: b
The costs that can be taken under the head “Materials” are : Cement, steel, Bricks and
Other building materials.
The estimated cost in 1990 = 80 + 45 + 12 + 18 = 155
The estimated cost in 1991 = 75 + 60 + 16 + 21 = 172
Cost of material rises by 5%,
Cost would rise by 0.05X (155 + 172) = Rs.16.35 lakhs.

Answer 8: b
Amount spent till 1990 = Rs.725.5 lakhs
Estimated Expenditure for 1991 = 209.5 lakhs.
Hence the increase in expenditure will be 209.5 on 725.5 = 28.87%.
