Show the answer and the worked solution
Correct answer: C. Friday
Worked solution
- The figures are 150, 200, 180, 220, 250 and 200.
- The largest is 250, on Friday.
Answer: Friday.
The idea
Read the caselet once and list the numbers in order before answering. A single scan then settles every question on the set.
Shortcut. Only days above the 200 average can win: Thursday (220) and Friday (250), and Friday is larger.
Common trap. Thursday — at 220 it is the first figure above 200 in a top-down scan, easy to settle on before reaching Friday's 250.
