Answer 1

Ans A: 26%.

Since 40% are male, 40 out of 100 employees are male and rest i.e. 60 employees are female.
Of the 40, 8 males go to night school and 30% of females i.e. 18 females go to night school.
So, a total 26 employees out of 100 employees i.e. 26% of employees attend night school.

Ans B. 990 minutes

Three lawn mowers operate for 930 minutes per day 900.
i.e. the three operate for a total of 3 x 930 = 2790 minutes.
Out of these if at least two of them mow for a minimum 900 minutes i.e.1800 minutes in total,
the third would be mowing for 2790 - 1800 = 990 minutes.

Ans C. 7/16

Total towels used in the thre days = 30 + 50 + 25 = 105.
So on an average 105 / 3 = 35 towels are in use.
i.e. 35 out of 80 i.e. 35 / 80 = 7/16 are in use during the 3 days.

Ans D. $29300

Total rent paid on the copier for 5 years i.e. 60 months
= 60 months x $600 = $36000.
Had it been purchased there would have been a maintenance charge of 60 x 100 = $6000 for the 5 years.
Also there would been a saving of $700.
So the copier would have cost = $36000 - $6000 - $700 = $29300.
