The table shows the monthly rainfall (in mm) in four regions over four months.
Which region recorded the lowest total rainfall?
Show answer & explanation
Correct answer: D
Explanation
Calculate the total rainfall for each region across all four months:
• Region 1: 120 + 130 + 140 + 110 = 500 mm
• Region 2: 115 + 122 + 128 + 105 = 470 mm
• Region 3: 110 + 118 + 120 + 108 = 456 mm
• Region 4: 118 + 126 + 135 + 112 = 491 mm
Therefore, Region 3 recorded the lowest total rainfall.
