Q.1. A hotel has 7 floors. The lobby, restaurant and gym are located on the ground floor. The guestrooms are on 1^st to 6^th floors.
If there are 35 standard rooms on each floor, how many standard rooms are there?

Number of floors = 7

Number of floors with standard rooms = 6 (excluding ground floor)

Number of rooms on each floor = 35

Total number of standar rooms = 35 x 6 = 210
There are 210 standard rooms.

If each standard room can fit 2 guests, what is the maximum number of guests that all the standard rooms can accommodate?

From above problem we found that total number of standard rooms = 210

Number of guests each room can occupy = 2

Total numbers of guests that can be accomodated = 210 x 2 = 420
The maximum number of guests that all the standard rooms can accommodate is 420 guests.

Each suite has 3 beds and there is a bed side table beside each side of each bed. How many bed side tables are there in all the suites?

Number of suites (standard rooms)= 210

Number of beds in each suite = 3

Total number of side tables = 3 x 2 x 210 =1260
There are 1260 bed side tables.

Q.4. A printing company has 6 printing machines.
Each printing machine costs $4,500. How much did the company pay for the machines?

Number of pages each printing machine has to print = 3,800 ÷ 5 = 760
Each machine will print 760 pages.

Q.6. A printing company has 6 printing machines.
There are 5 salespersons and 22 clients. If each client only deals with one salesperson and the clients are divided as equally as possible among the salespersons, how many salespersons are responsible for 5 clients?
