Question:

A five storey building has two floors in basement and three floors above the ground Total height of the building, from basement 30m and each floor is of the same the roof One person is standing on the lowest basement and another is standing at the roof to the top floor. Find at what distance both persons are standing from the ground?

Given:

• Number of Floors in Basement= 2
• Number of Floors above the ground= 3
• Total height of the building, from basement = 30m
• One person is standing on the lowest basement.
• Another is standing at the roof to the top floor.

To Find:

• Distance both persons are standing from the ground.

Solution:

Let, $\sf{x}$ be height of one floor. So,

$\mapsto\mathsf{Height\: of\: five\: floors=5x}$

We know, that total height of building (five floors) is 30m.

$\rightarrow\mathsf{5x=30m}$

$\rightarrow\mathsf{x=\large\frac{30}{5}}$

$\rightarrow\mathsf{x=6m}$

Also, One person is standing on the lowest basement. So,

$\\ \hookrightarrow\mathsf{Distance\: between\: ground\: and\: lowest\: floor=6\times 2m}$

$\\ \hookrightarrow\mathsf{Distance\: between\: ground\: and\:lowest\: floor=12m}$

Another person is standing at the top floor. So,

$\\ \dashrightarrow\mathsf{Distance\: between\: ground\: and\: top\: floor=6\times 3m}$

$\\ \dashrightarrow\mathsf{Distance\: between\: ground\: and\: top\: floor=18m}$
