Free RBS Numerical Reasoning Test Questions and Answers — Questions and Answers

Question 1: What was the highest number of students in any country that continued studying?

656 (Correct answer)
681
595
672

Correct answer: 656

Explanation: To find the answer you must work out the total number of students studying by interpreting the percentages: 41% = 0.41 1600 x 0.41 = 656 1650 × 0.36 = 594 1700 × 0.35 = 595 656 is the highest number.

Question 2: What was the difference in the number of graduates in employment between Vietnam and Cambodia?

150
140
145 (Correct answer)
155

Correct answer: 145

Explanation: To find the answer you should subtract the number of employed Cambodia graduates from the number of employed Vietnamese graduates: (1600 × 0.42) - (1700 × 0.31) = 145 OR 672 - 527 = 145

Question 3: If in South Korea the percentage of social science students was 34%, approximately what was the number of social science students in employment after graduating?

108
258 (Correct answer)
208
158

Correct answer: 258

Explanation: To find the answer you must, first, work out how many students studied Social Science and then apply the percentage of students employed: 1650 x 0.34 = 561 561 × 0.46 = 258.6 so the approximate answer is 258.

Question 4: How many graduates were unemployed in the 3 countries combined?

985
980 (Correct answer)
990
975

Correct answer: 980

Explanation: To find the answer you need to find the number of graduates who were unemployed using the given percentages and then add them all together: (1600 × 0.15) + (1650 × 0.16) + (1700 × 0.28) = 980 OR 240 + 264 + 476 = 980

Question 5: What is the difference in energy use between Plots 1 and 2 for the reception, meeting rooms, and office space combined?

10,150 kWh
11,050 kWh
1,900 kWh (Correct answer)
3,150 kWh

Correct answer: 1,900 kWh

Explanation: To find the answer we need to work out the energy use (in kWh) for the Reception, Meeting Rooms, and Office Space for both plots. When we have figures for each room we add up all of the Plot 1 figures and subtract the total of the Plot 2 figures: P1 Reception: 17000 × 0.15 = 2550 Meeting Room: 17000 x 0.09 = 1530 Office Space: 17000 × 0.41 = 6970 Total: 2550 + 1530 + 6970 = 11050 P2 Reception: 15000 x 0.14 = 2100 Meeting Room: 15000 x 0.1 = 1500 Office Space: 15000 × 0.37 = 5550 Total: 2100+ 1500 + 5550 = 9150 11050 - 9150 = 1900

Question 6: If the total energy usage is 6% less in a hypothetical Plot 3 than in Plot 2 as shown, what would the total difference in energy usage be between Plot 3 and Plot 1?

17.12%
17.1%
17.06% (Correct answer)
17.08%

Correct answer: 17.06%

Explanation: To find the answer we first need to calculate 6% of Plot 2's total energy and take this figure away from Plot 2's total. This will give us the total figure for Pot 3: 15000 x 0.06 = 900 15000 - 900 = 14100 Plot 3 total energy usage = 14100 kWH Next, we need to work out the percentage difference between Plot 1 and Plot 3. We do this by calculating what percentage Plot 3's total usage is of Plot 1's: (14100 / 17000) × 100 = 82.94 If Plot 1's total equals 100% then P3's total is 82.94% 100 - 82.94 = 17.06%

Question 7: Which room has the smallest difference in energy use between Plot 1 and Plot 2?

Reception
Kitchen
Toilet (Correct answer)
Office Space

Correct answer: Toilet

Explanation: P1 Toilet: 17000 × 0.06 = 1020 Reception: 17000 × 0.15 = 2550 Kitchen: 17000 × 0.29 = 4930 Office Space: 17000 x 0.41 = 6970 P2: Toilet: 15000 x 0.07 = 1050 Reception: 15000 x 0.14 = 2100 Kitchen: 15000 x 0.32 = 4800 Office Space: 15000 x 0.37 = 5550 T: 1050 - 1020 = 30 R: 2550 - 2100 = 450 K: 4930 - 4800 = 130 OS: 6970 - 5550 = 1420

Question 8: How much energy did the office space use in Plot 1 and Plot 2 combined?

12,520 (Correct answer)
12,220
12,620
12,120

Correct answer: 12,520

Explanation: To find the answer we need to calculate the total amount of energy used by both Office Spaces and then add them together: 17000 x 0.41 = 6,970 15000 x 0.37 = 5,550 6970 + 5550 = 12,520

Question 9: How many births occurred in 2018 in Italy and Australia combined?

1,246,040
1,346,040
1,146,040 (Correct answer)
Cannot say

Correct answer: 1,146,040

Explanation: To find the answer we must calculate how many births there were in both Italy and Australia and then add them together: 54800000 / 1000 = 54800 × 13.7 = 750,760 - births in Italy 48800000 / 1000 = 48800 × 8.1 = 395280 - births in Australia 395280 + 750760 = 1,146,040

Question 10: Which country had the highest number of people younger than 15 at the start of 2018?

Germany
UK
Italy (Correct answer)
France

Correct answer: Italy

Explanation: To find the answer we need to calculate what the 'percentage of under 15s' represents for each country and see which is the largest: G: 87.8 x 0.12 = 10.536 I: 54.8 x 0.21 = 11.508 F: 57.8 × 0.17 = 9.826 UK: 58.9 x 0.18 = 10.602 Therefore, Italy is the correct answer.

Question 11: What was the net effect of the UK population on the birth and death rates in 2018?

134,230 decrease
153,140 increase (Correct answer)
153,140 decrease
134,230 increase

Correct answer: 153,140 increase

Explanation: To find the answer to this question we need to identify the total population and how many 'births per 1000' minus 'deaths per 1000': Births 58,900,000 / 1000 = 58,900 58,900 × 13.9 = 818,710 Deaths 58,900,000 / 1000 = 58,900 58,900 x 11.3 = 665,570 Population Change 818,710 - 665,570 = 153,140 increase
