Answer 1

Answer:

Answer Is 12 Rs

Step-by-step explanation:

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
