C.P = Rs.650
profit made = 20%
Hence, S.P = C.P*(100+P)/100 = 650*120/100 = Rs. 780
This was his S.P after giving a discount of 20%.
Hence it was marked above its C.P
We know, M.P - M.P*discount% = S.P
M.P*(100-D)/100 = S.P
M.P*80/100 = 780
M.P = 780*100/80 = 975 Rs.
Hence, (Selling Price)S.P = 780 Rs
(Marked Price)M.P = 975 Rs.
Hope it helps
