Answers
Answer:
By selling 75 metres of cloth, a person gains the cost price of 15 metres. What is the gain percent?
It not he gain but he lose. So Let us solve:
Let Re 1 be the selling price of clothe per metre
Therefore selling price for 75 meters=75*1=Rs75
Since the selling price of 75 metres and a person gain the cost price of 15 metres.
Therefore the cost price of 15 metres= Rs 75
Therefore cost price per meter= 75/15=Rs 5
Therefore the cost price of 75 metres= 5*75= Rs 375
Therefore his loses= 375–75=Rs 300
Hence his loses% = 300*100/375= 80%
Answer:
The cost price of 1 metre = Rs. x
Cost price of 20 metre = Rs. 20x
Cost price of 50 metre = Rs. 50x
Given,
By selling 50 metres, he gains the cost price of 20
= Cost price of 50 metre + cost price of 20 metre
= 50x + 20x
= 70x
∴ Profit percent = [(Selling price of 50 metres - cost price of 50 metres)/Cost Price of 50 metres] × 100%
= [(70x - 50x)/50x] × 100%
= (2/5) × 100
= 40%
