IBM Company Numerical Ability Percentage

In a company printing work is done by two machine 5% of the work done by machine A are wasted, and 40% of work done by machine B are wasted. if the 80% of the total work is done by machine A. then what is the total percentage of wastage.

Read Solution (Total 2)

If total 100 units of job is done, then
80 units on machine A and 20 units of machine B.

wasted work by A = .05*80 = 4 units
wasted work by B = .4* 20 = 8 units

total wasted work = 12 units.

so 12% wastage
