Question

if selling price of 40 article is equal to cost price of 50 articles find the loss or gain percent​

Answer 1

S.P of 40 = C.P of 50

Let one article be ₹1

₹40(S.P) = ₹50(C.P)

If S.P < C.P, then it is loss

Loss= C.P - S.P

= 50 - 40

= ₹10

Loss percentage = (Loss / C.P) x 100

= (10/50) x 100

= 20% loss
