Meenakshi sells a pen for Rs.54 and loses of her outlay. Find (i) the cost price of the pen, and (ii) the loss per cent.

(i) Let × be the CP of Pen.

SP of Pen = x- 1x/10 = 54

X- X/10 = 54

9x/10 = 54

X= (54 × 10) / 9

= 60.

So, the Cost Price (CP) of Pen is Rs.60.

(ii) Loss = CP – SP

= 60 – 54

= 6

= 10%
