Answer 2

Hello..
Answer...

Let the cost price of the article be Rs. x

It is given that the man gained 10%.
This means that :
On As. 100 gain = Rs 10
:On Re 1 gain = Rs 10/100

On Rs x gain = Rs 10/100 multiplied by Rs x/10

We know that S. P. = C. P. + Gain

$495 = x + \frac{x}{10} \\ \\ = > 495 \times 10 = 10x + x \\ \\ = > 4950 = 11x \\ \\ = > \frac{11x}{11} = \frac{4950}{11} \\ \\ = > x = 450$


Hence, cost price of the article = Rs. 450.
