Instructions

Each of the six buildings, C, D, E, F, G and H has different number of floors. E has the second lowest number of floors. D has more number of floors than C and H but less than F. F does not have the maximum number of floors. H has less number of floors than both G and E. The building having second highest number of floors has 40 floors. C has 28 floors.

Question 22

# If the number of floors in buildings E + C is seven more than the number of floors in building F, how many floors are there in building E ?

Solution

E has the second lowest number of floors.

D has more number of floors than C and H but less than F, => F > D > C , H

Also, F does not have the maximum number of floors, => F has second highest number of floors and D has 3rd highest.

H has less number of floors than both G and E, => H has the least floors and G has the highest floors.

Combining above statements, we get :

$$\therefore$$ G > F > D > C > E > H

Number of floors of F = 40 and C = 28

Let number of floors in E = $$x$$

=> $$x + 28 = 40 + 7$$

=> $$x = 47 - 28 = 19$$
