The given graph shows rainfall in centimetres in the cities M, N, O and P from 2001 to 2005. Study the graph and answer the question.

Which year recorded highest total rainfall across all the cities?

Correct option is B

​Solution:

2001: 
Total = 160 + 160 + 130 + 100 = 550
2002:
Total = 160 + 150 + 140 + 120 = 570
2003: 
Total = 160 + 170 + 130 + 120 = 580
2004: 
Total = 150 + 160 + 120 + 120 = 550
2005: 
Total = 170 + 190 + 130 + 180 = 670

The year 2005 recorded the highest total rainfall across all cities, with a total rainfall of 670.​
