see this one below ; hope it helps

Answer 2

C.P. of 80 articles = Rs 2400

C.P. of 1 article = $\frac{2400}{80}$

We know that profit % = $\frac{S.P. - C.P.}{C.P.}$ * 100

16 = $\frac{S.P. - 2400}{2400}$ * 100

16* 24 = S.P. - 2400

⇒ S.P. = 2400 + 384

⇒ S.P. = 2784

This is the selling price of 80 articles

S.P. of 1 Article = $\frac{2784}{80}$

= Rs 34.8
