AFCAT Data Interpretation 5 — Questions and Answers
Question 1: A pie chart shows 720 soldiers by branch: Infantry=35%, Artillery=25%, Armoured=20%, Signals=12%, Engineers=8%. How many soldiers are in the Armoured branch?
- 144 (Correct answer)
- 180
- 252
- 86
Correct answer: 144
Armoured = 20% of 720 = 0.20 × 720 = 144 soldiers.
Question 2: A table shows flight delays (minutes) for 5 airlines: A=12, B=8, C=15, D=20, E=5. The authority flags delays above the mean as 'significant'. How many airlines are flagged?
- 2 (Correct answer)
- 3
- 1
- 4
Correct answer: 2
Mean = (12+8+15+20+5)/5 = 12; Airlines strictly above 12: C=15, D=20 → 2 airlines.
Question 3: A bar graph shows sorties flown per month: Apr=42, May=38, Jun=55, Jul=60, Aug=45. What is the percentage drop from July to August?
- 25% (Correct answer)
- 20%
- 15%
- 30%
Correct answer: 25%
Drop = (60−45)/60 × 100 = 15/60 × 100 = 25%.
Question 4: A table shows aircraft fuel consumption (L/hr) at altitudes: 5000 ft=400, 10000 ft=350, 20000 ft=280, 30000 ft=240, 40000 ft=220. What is the average fuel consumption across all altitudes?
- 298 L/hr (Correct answer)
- 310 L/hr
- 320 L/hr
- 275 L/hr
Correct answer: 298 L/hr
Average = (400+350+280+240+220)/5 = 1490/5 = 298 L/hr.
Question 5: A line graph shows aircraft serviceability rate (%): Jan=85, Feb=88, Mar=82, Apr=90, May=87, Jun=91. What is the difference between the highest and lowest serviceability rates?
- 9% (Correct answer)
- 6%
- 8%
- 7%
Correct answer: 9%
Highest = 91% (Jun), Lowest = 82% (Mar); Difference = 91 − 82 = 9%.
Question 6: Six cadets scored: 72, 85, 90, 68, 78, 95. What is their median score?
- 81.5 (Correct answer)
- 78
- 85
- 80
Correct answer: 81.5
Sorted: 68, 72, 78, 85, 90, 95; Median = (78+85)/2 = 81.5.
Question 7: A comparative table shows training hours — Ground: Batch A=120, Batch B=100; Flight: Batch A=80, Batch B=110. Which batch has more total training hours?
- Batch B (Correct answer)
- Batch A
- Both are equal
- Cannot be determined
Correct answer: Batch B
Batch A total = 200 hrs; Batch B total = 210 hrs — Batch B has more total training hours.
