Question

22. Shabana bought 16 dozen ball bens and sold them at a loss equal to S.P. of 8 ball pens,
Find
(i) her loss percent
(ii) S.P. of 1 dozen ball pens, if she purchased these 16 dozen ball pens for Rs 576.
​

Answer 1

Answer:

let cost of each pen =x

cost of 16 dozen ball pen i.e , 12×16 × x = 576

cost of each pen=3 (equation 1)

s.p of each pen= y

loss =8y

so, c.p=y+8y

from 1st

9y = 576

hence, y=576/9

so,y=64

loss 8×64

loss =512

loss%=512×100÷576

hence loss%=88.88
