Answer»

SP of paintings 924 each

Cost price of first painting CP1(1+20/100) = 924CP1(6/5) = 924CP1 = 154*5 = 770

Cost price of first painting CP1(1-20/100) = 924CP1(4/5) = 924CP1 = 231*5 = 1155

Total SP = 924*2 = 1848Total CP = 770 + 1155 = 1925

Loss % = (CP - SP /CP) *100 = (1925-1848/1925)*100 = 7700/1925 = 700/175 = 4%
