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?

Accepted Answer

144

Answer

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?

Accepted Answer

2

Answer

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?

Accepted Answer

25%

Answer

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?

Accepted Answer

298 L/hr

Answer

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?

Accepted Answer

9%
