gained 28% and on other he lost 12%. What is his overall gain or loss percent, correct to one decimal place?Solution
Total SP of both articles = 1936 × 2 = 3872 CP of first articles = 1936 × (100/128) = 1512.5 CP of second articles = 1936 × (100/88) = 2200 Total CP = 2200 + 1512.5 = 3712.5 Profit = 3872 – 3712.5 = 159.5 ∴ Profit percentage = 159.5/3712.5 × 100 = 4.3%
