Question
Last year Mr. A bought two paintings. This year he sold
them for Rs, 20,000 each. On one, he made a 25% profit and on the other he had a 25% loss. Then his net profit or loss isSolution
SP of each painting = 20000 profit on 1st painting = 25% loss on 2nd painting = 25% CP + profit = SP profit = (profit percentage/100)× CP CP + 1/4CP = SP 5/4CP = SP {SP =20000} CP = 4/5 × 20000 = 16000 CP - loss = SP loss = (loss percentage / 100) × CP CP – 1/4CP = SP 3/4 CP = SP {SP =20000} CP = 4/3 × 20000 = 26666.66 Total CP = 16000+26666.66 = 42666.66 total SP = 20000+20000 = 40000 loss = 42666.66 - 40000 = 2666.66 loss is more than 2000
