Study the given 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 actual production of ACs in February is what per cent less than the average target production of ACs over the period of five months (correct to the nearest integer)?

30%

Actual production of ACs in February = 50

Average target production of ACs over all 5 years = \(\frac{60+30+80+90+100 }{5}\)

= \(\frac{ 360 }{5}\)

= 72

required percentage = \(\frac{72-50 }{72}\) × 100

= 30.55%

= 30%    (correct to the nearest integer)
