Q1: The floor slab of a building is supported on reinforced cement floor beams. The ratio of the end and intermediate spans is kept

ANS:C - 0.9

The ratio of the end span to the intermediate span in a floor slab supported on reinforced cement floor beams is commonly determined based on structural considerations and design requirements. While there is no universally fixed ratio, the selection of an appropriate ratio depends on factors such as load distribution, deflection control, and overall structural stability. Typically, the end span is shorter than the intermediate span to provide adequate support near the beam ends and ensure uniform load distribution across the slab. In practice, the ratio of the end span to the intermediate span may vary depending on specific project requirements and design preferences. However, a common guideline is to keep the end span shorter than the intermediate span. Therefore, the correct answer could be "none of these" as the specific ratio may not be accurately represented by any of the provided options. The selection of the ratio should be made based on the structural analysis and design considerations specific to the project.
