In the table, production and sale (in 1000 tons) of a certain product of a company over 5 years is given.  Study the table and answer the question.

Find ratio of total production to total sale over all years?

144 : 125

Total production = 1250 + 1400 + 1450 + 1500 + 1600 = 7200

Total sale = 1000 + 1300 + 1100 + 1450 + 1400 = 6250

Ratio → 7200  :   6250

              144  :  125
