Study the graph which shows the target and actual production of ACs, (in thousands) of a factory over five months and answer the question that follows.

The total target production of ACs in February, March, April and May is what percent less than the total actual production of ACs over five months? (correct to one decimal place)

28.6%

Total target production of ACs in February, March, April and May 

= ( 30 + 80 + 90 + 100 )

= 300

 Total actual production of ACs over five months

= ( 70 + 50 + 100 + 80 + 120 )

= 420

Required percentage = \(\frac{420-300 }{420}\) × 100

= \(\frac{120 }{420}\) × 100

= 28.6%
