Comprehension Passage
Directions: Answer the questions based on the information given below.
The following bar graph shows the number of steps in each stair in five different houses (A, B, C, D, and E) and the number of floors in each house.
Note :
(1) Assume the ground floor as the 'first' floor and above all the given floors, there is a 'roof'. For example, if there is a '4-floor' house then there are four floors and one roof. Between two adjacent floors and the topmost floor and the roof, there is one stair each which contains a certain number of steps as given in the bar graph.
(2) Each stair in the same house has the same number of steps.
(3) All the values presented in the graph are integer values.
(4) The value of (Z + K) is equal to the closest integer value of [(17576)0.33 + (5832)0.33 + (2744)0.33]/√450.
(5) 'K' is the smallest prime number.
What is the respective ratio between the total number of steps in house 'C' from ground floor to roof in stairs in that in house 'D' ?
