Infosys Data Interpretation Questions and Answers Quiz – 1

Average of company 'A' over the years
=\frac{30 + 50 + 60 + 40 + 70 + 60 + 75}{7}
=\frac{385}{7} = 55
None of the years of company 'A' has imports 55.

\frac{80 - 40}{40} \times 100 = 100\%

Energy used for others purposes = 20°
Total Energy used for 4 major areas = 110° + 105° + 45° + 80° = 340°
∴ Required percentage
=\frac{20}{340}\times 100 = 5.88\% \approx 6\%

As per the given data given the difference between energy used for domestic purposes and other purposes = 45° - 20° = 25°
Now, 360° is equivalent to 600 million tonnes
Then, 25° = \frac{600}{360}\frac 25
= 41.67 million tonnes

Empolyees 'A' -- \frac{80}{900}\times 100 = 8.88\%
Empolyees 'B'-- \frac{40}{500} \times 100 = 8\%
Empolyees 'C' -- \frac{150}{1500} \times 100 = 10\%
Empolyees 'D' -- \frac{80}{700} \times 100 = 11.42\%
Empolyees 'E'-- \frac{100}{1000} \times 100 = 10\%
Employee 'D' earns maximum bonus in comparison to his income.

= \frac{180}{200} \frac 100 = 90\%

Difference in cost in Jalandhar = 160 - 60 = Rs 100
Difference in cost in in Delhi = 130 - 90 = Rs 40
Difference in cost in Chandigarh = 180 - 120 = Rs 60
Difference in cost in Hoshiarpur = 90 - 30 = Rs 60
Difference in cost in Ropar = 40 - 20 = Rs 20
So, second lowest Difference in cost in Delhi.

Cost of 1 kg guava in Jalandhar = Rs 60
And cost of 2 kg grapes in Chandigarh = 2 x 90 = Rs 180
∴ Required percentage
= \frac{60}{180} \times 100 = 33.33 \approx 34\%

Total purchase of items made by R = 12% of the total purchase
Total purchase of items made by T = 16% of the total purchase
Similarly,
Total purchase made by P = 18% of the total purchase
Total purchase made by S = 15% of the total purchase
Reqd difference = (15% + 18%) of total purchase - (16% + 12%) of total purchase = (33% - 28%) of total purchase = 5% of total purchase
= 5% of 4700 = 235.

Total purchase made by P, R and T together = (18 + 12 + 16)% of total purchase = 46% of total purchase
And the total purchase made by S and Q together = (15 + 35)% of total purchase = 50% of total purchase
∴ Reqd ratio = \frac{46\% \text{ of total purchase }}{50\% \text{ of total purchase }} = \frac{46}{50}
= 23 : 25.
