Solution

C.P. of one article = ₹ 450

C.P. of 30 articles = ₹ 450 × 30 = ₹ 13500

C.P. of `1/3` articles = `₹450xx30/3`

= ₹ 4500

Loss of = 6%

∴ S.P. of 10 articles `=("C.P."xx(100-"Loss%"))/100`

`= ₹(4500 xx (100-6))/100`

`= ₹(4500 xx 94)/100`

= ₹ 4230

C.P. of remaining articles = ₹ 450 × 20

= ₹ 9000

Profit on the whole = 10%

∴ Total S.P. of 30 articles

`=₹(13500xx(100+10))/100`

`=₹(13500xx110)/100`

= ₹ 14850

∴ S.P. of the remaining 20 articles.

= ₹ 14850 − ₹ 4230 = ₹ 10620

∴ S.P. of 1 article = `₹10620/20` = ₹ 531
