sp1. = 3605
profit = 15%
so cp1 = (sp × 100)/(100 + profit%)
= (3605 × 100)/(100 + 15)
= (3605 × 100)/115
= 31.347 × 100
= 3134.7
sp2 = 3605
loss = 9%
cp2 = (sp × 100)/(100 - loss%)
= (3605 × 100)/(100 - 9)
= (3605 × 100)/91
= 39.6 15 × 100
= 3961.5
total cp = 3134.7 + 3961.5 = 7096.2 =
total sp = 3605 × 2 = 7210
overall loss = 7210 - 7096.2 = 113.8
profit = 15%
so cp1 = (sp × 100)/(100 + profit%)
= (3605 × 100)/(100 + 15)
