Shabana Bought 16 Dozens Ball Pens And Sold Them At A Loss Of To S.p Of 8 Ball Pens. Find: (i) Her Loss Percent (ii) P Of 1 Dozen Ball Pens, If She Purchased These 16 Dozens Ball Pens For Rs.576

Answer»

(i) Number of pens bought = 16(12) = 192

Let S.P of one pen be Rs. x

Therefore, S.P of 192 pens = 192x

C.P of 8 pens = Rs. 8X

It is given that S.P of 8 pens is equal to the loss on SELLING 192 pens.

Therefore, loss= Rs.8x

C.P of 192 pens = Rs 576

Loss = C.P –S.P

= 8x = 576 – 192x200

= 576 x = 576200

=x= 2.88

Therefore, loss= RS.23.04

Loss% = 4%

(II) P of 1 pen = Rs.2.88

Therefore, S.P of 1 dozen pens = 12x = 12(2.88)

= Rs.34.56

(i) Number of pens bought = 16(12) = 192

Let S.P of one pen be Rs. x

Therefore, S.P of 192 pens = 192x

C.P of 8 pens = Rs. 8x

It is given that S.P of 8 pens is equal to the loss on selling 192 pens.

Therefore, loss= Rs.8x

C.P of 192 pens = Rs 576

Loss = C.P –S.P

= 8x = 576 – 192x200

= 576 x = 576200

=x= 2.88

Therefore, loss= RS.23.04

Loss% = 4%

(ii) P of 1 pen = Rs.2.88

Therefore, S.P of 1 dozen pens = 12x = 12(2.88)

= Rs.34.56
