Answer 1

Number of packets = 250 Cost of each packet= Rs 8  Total cost price= 250×8= Rs 2000 70% of the 250 packets= 250×70100=175   Cost of each packet of 175 is = Rs 11 Total cost of 175 packets= 175×11= Rs 1925  Remaining packets = 250−175= 75 Cost of each 75 packets Rs 9  Total cost = 75×9= Rs 675  Total selling price = Rs 1925+Rs 675 = Rs 2600  Gain = Selling Price Cost Price= Rs 2600 − Rs 2000=Rs 600Gain % = Gain cost price ×100= 600÷2000×100=30%

Answer 2

total cost price of 250 packets of blades at the rate of 8 rupees is 250×8= 2000
SP of 70% of packet that is 175 packets is 175×11=1925
also the SP of Remaining 75 packet is 75 × 9 = 675
total SP of 250 packets of blades is 1925+675 =2600
gain equals to SP - CP
2600- 2000
600
gain% = (gain/ CP) ×100
= (600/2000) ×100
= 30%
