Question

1 in a mall 20% area is occupied by eateries,60% area is open.In the remaining area of 1600 sq meter there are different showrooms.What is the total area occupied by the mall?

Answer 1

$\textbf{ANSWER:}$

Let the total area occupied by the mall be x.

Then:

Area occupied by the eateries =
$\frac{20}{100} x = \frac{x}{5}$


Open area =
$\frac{60}{100} x = \frac{3x}{5}$

Also, in 1600 sq. m area, showrooms are constructed.

Therefore, ATQ:

$\frac{x}{5} + \frac{3x}{5} + 1600 = x \\ \\ \frac{x + 3x + 8000}{5} = x \\ \\ 4x + 8000 = 5x \\ \\ 5x - 4x = 8000 \\ \\ x = 8000 \: {m}^{2}$


8000 sq. m is the answer...
