10. Rajeshwar bought 16 dozen ballpoint-pens and sold them one by one. Due to a calculation mistake
in fixing the selling price, he lost an amount equal to the S.P. of 4 dozen pens. Find his loss %.
Find the S.P. of one dozen pens, if he purchased these 16 dozen pens for 240.
​

Answer 1

Answer:

Let the S.P. of one dozen pens be Rs. x.

Then S.P. of 16 dozen pens = Rs. 16x, Loss = S.P. of 4 dozen pens = Rs. 4x

∴ C.P. = S.P. + Loss = Rs. 16x+ Rs. 4x= Rs. 20x

∴ Loss per cent =(

20x

4x

×100)=20%

C.P. of 16 dozen pens = Rs. 240, Loss =20%

∴

100

240×80

= Rs. 192

∴ S.P. of 1 dozen pens = Rs.

16

192

= Rs. 12

This is the answer
