Answer:
loss percent is 4 sp for 1 dozen pens is 34.56
Step-by-step explanation:
Number of pens bought =16 ×12 =192
Let the selling price be x per pen. so the price of 192 pens =192x
S.P. of 8 pens = 8 × x = 8 x = loss
Cost price of 192 pens = Rs. 576
Therefore loss = C.P. – S.P.
8 x = 576 – 192 x
200 x = 576
x = 576 / 200 = 2.88
Therefore loss = 8 × 2.88 = 23.04 Rs.
loss percent = loss × 100 / C.P.
= 23.04 × 100 / 576 = 4 percent loss
(2)
Sp of 1 pen x = 2.88
Therefore S.P. of 1 dozen pens = 12 × 2.88 = Rs. 34.56
