a man buys 100 items at rupees 20 per item and sells 40% of item at rupees 21 per item and rest 60% at Rs 16 per item find his gain or loss percentage

Answer»

Cost price of 1 item = 20 Rs
Cost price of 100 items = 100 × 20=2000 Rs
40% of items = (40 /100)×100 =40 items
60 % of items = (60/100) ×100=60 items
selling price of 40 items = 40× 21 =840 Rs
selling price of 12 items = 60 ×12=720 Rs
Total selling price =840 + 720=1560 Rs
Loss =2000 - 1560=440 Rs
loss percentage = (loss/ C.P. )×100
=(440×100)/2000=22%
