Directions: There are 5 different Buildings A, B, C, D and E and the number of Total number of floors and number of vacant floors given. Read the graph carefully and answer the given questions
Total Number of floors = Number of Vacant Floors + Number of Occupied floors
Formula Used:
Number of Occupied floors = Total Number of floors - Number of Vacant Floors
Calculation:
Name of the buildings |
Total Number of floors in Buildings |
Number of Vacant Floors in Buildings |
Number of Occupied floors on Buildings |
A |
800 |
200 |
600 |
B |
1400 |
280 |
1120 |
C |
600 |
320 |
280 |
D |
1000 |
400 |
600 |
E |
1200 |
360 |
840 |
The total number of occupied floors of buildings B and C together = 1120 + 280 ⇒ 1400
The total number of occupied floors of building D and E together = 600 + 840 ⇒ 1440
The difference between (D + E) - (B + C) = 1440 - 1400 ⇒ 40
∴ The difference between the total number of occupied floors of buildings B and C together and that of buildings D and E together is 40
