A table shows the population of Town X as 8,000 in 2018 and 9,200 in 2022. What is the percentage increase in the population over these four years?
Explanation: The population increase is 1,200 (9,200 minus 8,000). The percentage increase is calculated as (1,200/8,000) multiplied by 100, which equals 15%. The other options are incorrect: 12.5% and 10% underestimate the increase, while 18% overestimates it. Only 15% accurately reflects the population change.
A bar graph displays the monthly sales (in units) for a company: January - 500, February - 650, March - 450, and April - 600. Which month showed the highest sales?
Explanation: February had the tallest bar with 650 units sold, making it the month with the highest sales. January had 500, March had the lowest at 450, and April recorded 600. Choosing April, January, or March ignores the higher value observed for February.
In a pie chart showing the market share of four companies, Company A holds 25%, Company B 40%, Company C 20%, and Company D 15%. Which company has the second largest market share?
Explanation: Company B has the largest market share at 40%, and Company A is next with 25%. Company C and D have smaller shares of 20% and 15%, respectively. Choosing Company C or D would mean selecting lower values, while Company B is actually the largest, not second.
A table lists student exam scores: Alex 78, Sam 82, Kim 75, and Lee 89. Who scored the highest among them?
Explanation: Lee scored 89, the highest in the list, as shown directly in the table. Sam scored 82, which is less than Lee’s score, while Alex and Kim scored even lower. Picking Sam, Kim, or Alex overlooks the greater value achieved by Lee.
A line graph shows temperatures for five days: Mon 22°C, Tue 24°C, Wed 20°C, Thu 23°C, Fri 26°C. What is the overall trend from Monday to Friday?
Explanation: From Monday to Friday, the temperature rises from 22°C to 26°C, showing an overall increase. There is a dip on Wednesday but, considering start and end points, the general trend is upward. 'A decrease followed by an increase' describes the midweek dip but misses the overall direction, while 'No clear trend' and 'Temperatures remain constant' are inaccurate given the data change.
