Table: Monthly rainfall in a town, in millimetres — June 250, July 400, August 500, September 350. What was the total rainfall from June to September?
Correct answer: D. 1,500 mm
Total = 250 + 400 + 500 + 350 = 1,500 mm. Pairing 250 + 350 = 600 and 400 + 500 = 900 makes the sum easy. Keep the unit, millimetres, with the answer.
