Answer» let the C.P = x so, S.P = C.P +20% of C.P = 1.2X so, when 20% discount was given on 1.2x the new selling price becomes S.P' = 1.2x-(20% of 1.2x) = 0.8*1.2x = 0.96x so, the C.P = x and.. S.P is 0.96x hence C.P > S.P So, he lost.. option B

Answer»

let the C.P = x

so, S.P = C.P +20% of C.P = 1.2X

so, when 20% discount was given on 1.2x

the new selling price becomes

S.P' = 1.2x-(20% of 1.2x) = 0.8*1.2x = 0.96x

so, the C.P = x and.. S.P is 0.96x

hence C.P > S.P

So, he lost..

option B
