Numerical Reasoning Data Interpretation

Question 1

A table shows sales data: Jan=120, Feb=150, Mar=90, Apr=180, May=160, Jun=200. What is the average monthly sales for the first half of the year?

Accepted Answer

133.3

Answer

Sum = 120+150+90+180+160+200 = 900; average = 900/6 = 150, wait: 900/6 = 150. Let me recalculate: 120+150=270, +90=360, +180=540, +160=700, +200=900; 900/6 = 150.

Question 2

A pie chart shows department budgets: Marketing 25%, IT 30%, HR 15%, Operations 20%, R&D 10%. If the total budget is $2,000,000, how much is allocated to IT?

Accepted Answer

$600,000

Answer

IT gets 30% of $2,000,000 = 0.30 × $2,000,000 = $600,000.

Question 3

A bar chart shows quarterly revenue: Q1=$450K, Q2=$520K, Q3=$480K, Q4=$550K. By what percentage did revenue increase from Q1 to Q4?

Accepted Answer

22.2%

Answer

Increase = (550−450)/450 × 100 = 100/450 × 100 ≈ 22.2%.

Question 4

A table shows test scores for 5 students: 72, 85, 91, 68, 79. What is the median score?

Accepted Answer

79

Answer

Sorted scores: 68, 72, 79, 85, 91; the middle (3rd) value is 79.

Question 5

A line graph shows website visitors over 4 weeks: Week1=1,200, Week2=1,500, Week3=1,350, Week4=1,800. What is the range of weekly visitors?

Accepted Answer

600

Answer

Range = maximum − minimum = 1,800 − 1,200 = 600.
