Question 64

The given Bar Graph presents the Target and Actual production of AC Machines (numbers in thousands) of a factory over five months.

The total target production of AC Machines in February, April and May was what percentage less than the total actual production of AC Machines overall the five months(correct to one decimal place)?

Solution

The total target production of AC Machines in February, April and May was considered has final=February+April+May=30+90+100=220

the total Actual production of AC Machines overall the five months is considered has initial=70+50+100+80+120=420

we know that %decrease=$$\frac{initial-final}{initial}\times100$$

= $$\frac{420-220}{420}$$×100

= $$\frac{200}{42}$$×10

=$$\frac{2000}{42}$$

=47.61
