A bus completes a journey in 8 hours at 54 km/h. What speed is needed to complete the same journey in 6 hours?
Answer: 72 km/h
Distance = 54 × 8 = 432 km; New speed = 432 ÷ 6 = 72 km/h.
A store offers a 35% discount on a jacket originally priced at $120. What is the sale price?
Answer: $78
Discount = 0.35 × $120 = $42; sale price = $120 − $42 = $78.
A box contains 480 items. If 12.5% are defective, how many items are not defective?
Answer: 420
Defective = 0.125 × 480 = 60; non-defective = 480 − 60 = 420.
A train passes a 600 m bridge in 30 seconds and a 300 m bridge in 18 seconds. What is the train's speed in m/s?
Answer: 25 m/s
Setting (L+600)/30 = (L+300)/18 gives L = 150 m; Speed = (150+600)/30 = 25 m/s.
What number is missing to take the place of the question mark?
Answer: 22
To solve this numerical reasoning question, one must identify the underlying mathematical pattern or rule governing the sequence or arrangement of numbers. Once the pattern, such as addition, subtraction, multiplication, division, or a combination of operations, is deciphered, it can be applied to find the missing number. In this specific case, applying the identified pattern reveals that 22 is the correct missing value.
A bar chart shows quarterly revenue: Q1=$450K, Q2=$520K, Q3=$480K, Q4=$550K. By what percentage did revenue increase from Q1 to Q4?
Answer: 22.2%
Increase = (550−450)/450 × 100 = 100/450 × 100 ≈ 22.2%.
A rectangle has a perimeter of 56 cm. If its length is 3 times its width, what is the area?
Answer: 147 cm²
Width = 7 cm, length = 21 cm; area = 7 × 21 = 147 cm².
What number is missing to take the place of the question mark?
Answer: 4
To find the missing number, one must identify the underlying mathematical or logical pattern governing the sequence or arrangement presented. By analyzing the relationships between the existing numbers, the pattern can be deduced and applied to determine the value that correctly fills the question mark's position. In this case, applying the specific pattern reveals the missing number is 4.
A cyclist covers 45 km in 3 hours. At the same speed, how long will it take to cover 75 km?
Answer: 5 hours
Speed = 45 ÷ 3 = 15 km/h; Time = 75 ÷ 15 = 5 hours.
A laptop costs $800. A 15% sales tax is applied, then a $50 rebate is given. What is the final price?
Answer: $870
Price after tax = 800 x 1.15 = $920; after rebate = $920 minus $50 = $870.
A company's workforce is 60% female. If there are 270 female employees, what is the total number of employees?
Answer: 450
Total = 270 / 0.60 = 450 employees.
If 8 items cost $52, what is the cost of 15 items at the same unit price?
Answer: $97.50
Unit price = $52 ÷ 8 = $6.50; 15 × $6.50 = $97.50.
If the cost of 8 notebooks and 5 pens is $31, and 4 notebooks and 5 pens cost $19, what is the cost of one notebook?
Answer: $3
Subtracting the second equation from the first: 4 notebooks = $12; one notebook = $3.
A business spends $12,000 on advertising and generates $84,000 in new revenue. What is the return on advertising spend (ROAS)?
Answer: 7
ROAS = Revenue ÷ Ad Spend = $84,000 ÷ $12,000 = 7.
A company's revenue grew from $480,000 to $600,000. By what percentage did it grow?
Answer: 25%
Growth = (600,000 - 480,000) / 480,000 × 100 = 120,000 / 480,000 × 100 = 25%.
A table shows quarterly profits: Q1=$42K, Q2=$58K, Q3=$37K, Q4=$63K. By how much does Q4 exceed the annual average?
Answer: $13K
Average = ($42K+$58K+$37K+$63K)/4 = $50K; Q4 exceeds by $63K−$50K = $13K.
How much would a consumer have paid if they initially chose the Orange package but then, after six months, elected to switch to the White package, which is less expensive, to finish their contract?
Answer: $330
To calculate the total cost, first determine the monthly cost of the Orange package and the White package. Calculate the cost for the first six months using the Orange package's monthly rate. Then, calculate the cost for the remaining duration of the contract (typically six months for a standard year-long contract) using the less expensive White package's monthly rate. Sum these two amounts to find the total payment, which is $330.
An investment of $5,000 earns simple interest at 6% per year. What is the total value after 3 years?
Answer: $5,900
Simple interest = P × r × t = $5,000 × 0.06 × 3 = $900; total = $5,000 + $900 = $5,900.
A table shows production output: Mon=240, Tue=310, Wed=280, Thu=295, Fri=325. Which two consecutive days show the largest increase?
Answer: Mon to Tue
Mon→Tue: +70; Tue→Wed: −30; Wed→Thu: +15; Thu→Fri: +30; the largest increase is Mon to Tue at 70 units.
A store sells 3 items for $7.50. At this rate, how much would 20 items cost?
Answer: $50.00
Unit price = $7.50 ÷ 3 = $2.50; 20 items = 20 × $2.50 = $50.00.
