Given,
CP of cosmetics = Rs 360 per dozen
SP of a pair of cosmetics = Rs 80
To find,
The gain percent
Solution,
1 dozen = 12 items
CP of 1 cosmetic = 360/12 = Rs 30
SP of 1 cosmetic = 80/2 = Rs 40
Profit = SP-CP
= Rs 40 - Rs 30
= Rs 10
Profit percentage is given by :
![\%=\dfrac{profit}{CP}\times 100\\\\=\dfrac{10}{30}\times 100\\\\=33.34\%](https://tex.z-dn.net/?f=%5C%25%3D%5Cdfrac%7Bprofit%7D%7BCP%7D%5Ctimes%20100%5C%5C%5C%5C%3D%5Cdfrac%7B10%7D%7B30%7D%5Ctimes%20100%5C%5C%5C%5C%3D33.34%5C%25)
So, the profit percentage is 33.34%.
