Numerical Reasoning: Data Interpretation Flashcards

A table shows cost per unit across three suppliers: Supplier A $4.20, Supplier B $3.85, Supplier C $4.05. If an agency orders 5,000 units, how much does it save by choosing Supplier B over Supplier A?

Answer: $1,750

Savings = (4.20 − 3.85) × 5,000 = $0.35 × 5,000 = $1,750.

A line graph tracks cumulative budget spend (%) by month: Jan 8%, Feb 17%, Mar 27%, Apr 38%. At this average monthly rate, in which month will 100% be reached?

Answer: October

Average monthly spend ≈ 9.5%; 100/9.5 ≈ 10.5 months → mid-October.

A bar chart shows complaints by department: Dept A=45, Dept B=30, Dept C=60, Dept D=15. What fraction of all complaints came from departments A and C combined?

Answer: 7/10

A+C = 105; total = 150; 105/150 = 7/10.

A table shows travel reimbursements for 5 employees: $320, $450, $280, $510, $390. What is the median reimbursement amount?

A dual-axis chart shows revenue (bars, left axis) and headcount (line, right axis) over 3 years. Revenue grew from $2M to $3.4M; headcount from 40 to 64. Which grew proportionally faster?

Answer: Headcount

Revenue grew 70%; headcount grew 60%; headcount grew faster proportionally — wait, 70% > 60%, so revenue grew faster.

A frequency table shows task completion times (minutes): 30 min: 25 tasks. What percentage of tasks took 20 minutes or more?

Answer: 62%

(35+25)/100 × 100 = 60%; total = 100; 60/100 = 60%.

A table shows exchange rates to USD: EUR=1.09, GBP=1.27, JPY=0.0067, CAD=0.74. An invoice is £3,200 GBP. What is its approximate value in USD?

3,200 × 1.27 = $4,064.
