Question

a man sold an article for 6270 and lost 1/20of the cost price. find the cost price.

Answer 1

Here is your answer..

Solution:-
He sold an article for ₹6270
Means SP = ₹6270

Let the CP be x.
So,
Loss is equal to 1/20 of CP
$= > \frac{1}{20} \times x \\ = > \frac{1}{20} x$
We know that,
Loss =CP -SP
$= > \frac{1}{20} x = x -6270$
$= > \frac{1}{20}x - x = - 6270 \\ = > \frac{1x - 20x}{20} = - 6270$
$= > \frac{ - 19}{20}x = - 6270 \\ = > x = \frac{ - 6270 \times 20}{ - 19} \\ = > x = 330 \times 20 \\ = > x = 6600$
Therefore,
CP = ₹6600
