Question

A hotel has 5 floors with 49 rooms on each floor. 4 people can stay in each room. What is the estimated number of people the hotel can accomodate?

• A. 1000
• B. 2000
• C. 1500
• D. 1200

Answer 1

The correct option is A 1000

Number of floors $=5$
Number of rooms $=49$

Approximate number of rooms $=50$
Number of people that can stay in each room $=4$
Estimated number of people the hotel can accomodate $=5\times 50\times 4=5\times 4\times 50$

By grouping 5 and 4 we get $5\times 4=20$

Estimated number of people the hotel can accomodate $=5\times 4\times 50=20\times 50=1000$
