# Find the whole quantity if 5% of it is 600.

Hint – In this question let the whole quantity be x. Use the constraint of question of 5% it being 600 by applying the percentage formula, and get the answer.

Complete step-by-step solution -
Let the whole quantity be x.
Now it is given that 5% of the whole quantity is 600.
So construct the linear equation according to this information.
Therefore 5% of x = 600
$\Rightarrow \dfrac{5}{{100}} \times x = 600$
Now simplify the above equation we have,
$\Rightarrow x = \dfrac{{600 \times 100}}{5} = 600 \times 20 = 12000$.
So the whole quantity is 12000.
So this is the required answer.

Note – In this question the key concept was of percentage formula. In simple words percent means per 100. To express a number between zero and one. Percentage formula is defined as a number represented as fraction of 100. Application of it while solving problems of such kinds is very helpful.
