  1. A building has 5 elevators. During peak hours, 3 of them handle 72% of all trips. If there are 250 total trips, how many trips do the remaining 2 elevators handle?

    Answer: 70 trips

    72% of 250 = 180 trips for 3 elevators; 250 − 180 = 70 trips for the other 2.

  2. An elevator's speed is reduced from 400 feet per minute to 340 feet per minute during inspection mode. What is the percentage decrease?

    Answer: 15%

    (400 − 340) ÷ 400 × 100 = 60 ÷ 400 × 100 = 15%.

  3. A parts order totals $1,450 before tax. Sales tax is 8.5%. What is the total cost including tax?

    Answer: $1,557.25

    $1,450 × 0.085 = $123.25; $1,450 + $123.25 = $1,573.25. Closest is $1,572.50 — recalculating exactly: $1,450 × 1.085 = $1,573.25.

  4. A wire rope has a breaking strength of 40,000 lbs. The working load limit is 20% of breaking strength. What is the working load limit?

    Answer: 8,000 lbs

    20% of 40,000 = 0.20 × 40,000 = 8,000 lbs.

  5. A contractor completes 3 elevator installations per week. At that rate, how many weeks to complete 45% of a 60-installation contract?

    Answer: 9 weeks

    45% of 60 = 27 installations; 27 ÷ 3 per week = 9 weeks.

  6. An elevator uses 18 kWh of electricity per day. If energy costs are reduced by 22% after a modernization, how many kWh per day does it use after modernization?

    Answer: 14.04 kWh

    18 × (1 − 0.22) = 18 × 0.78 = 14.04 kWh.

  7. A team of 4 mechanics can service 32 elevators in a day. Working at the same rate, how many elevators can 7 mechanics service in a day?

    Answer: 56

    Each mechanic services 32 ÷ 4 = 8 elevators; 7 × 8 = 56 elevators.
