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

1 dozen = 12 pens

16 dozen = ?

16 × 12 = 192

cost of 1 pen = 576/192

= 3 rs

i) 8×3 =24 => loss

loss % = 100×sp/ 100-loss

100×3/100-24

= 12.5

ii)1 pen = 3rs

12 pen = ?

12×3 =36 rs
