Correct answer: C. March
Worked solution
- January: 400 + 300 + 500 = 1,200.
- February: 450 + 350 + 400 = 1,200.
- March: 500 + 400 + 600 = 1,500.
- April: 550 + 450 + 450 = 1,450.
The highest is March.
Answer: March.
The idea
Add every row before deciding. April has the highest figures in two of three columns yet still falls short of March.
Shortcut. Compare March and April directly: April gains 50 in A and 50 in B but loses 150 in C, so March is ahead by 50; January and February are far lower.
Common trap. "April" — it leads in two of the three columns, but Unit C's drop from 600 to 450 leaves its total at 1,450 against March's 1,500.
