Profit or loss?Date: 6/17/96 at 5:17:51 From: Anonymous Subject: Profit or loss? word problem Mr Li paid $120 for a basket of 40 durians. He found that 4 of them were bad and threw them away. He sold 2/3 of the remaining durians at a profit of 20% and the rest at a loss of 5%. What was his profit or loss? Date: 6/17/96 at 8:5:26 From: Doctor Anthony Subject: Re: Profit or loss? word problem His costs were 120/40 = $3 each He lost 4 immediately so he sold 36 durians in all. 2/3 of these = 24 durians he sold at 1.20*3 = $3.60 each 1/3 of these = 12 durians he sold at 0.95*3 = $2.85 each Total income from sales = 24*3.60 + 12*2.85 = $120.6 Profit was $0.60 Percentage profit = (actual profit)/(original cost)*100 = (0.6/120) * 100 = 1/2 % profit. -Doctor Anthony, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
