article for the price C paid, what would have been his loss or gain per cent?​

Answer 1

Answer:

Step-by-step explanation:C pays rupees 216

B sells at 10% loss , this means 90% of cost price is 2016

90x/100 =216

90x=21600

X=21600/90

X= 240

Therefore, cost price for B = Rs.240

Since A sells for 20% profit, 120% of cost price =240

120/100 × y = 240

12y/10 = 240

12y=2400

Y= 2400/12

Ans. Cost price for A = Rs. 200

Answer 2

Answer:

Rs.270

Step-by-step explanation:

Case I

Profit = 20%

SP = CP[(100 + P%)/100]

     = CP[(100 + 20)/100]

     = CP x 120/100

SP = 6/5 CP

Case II

Loss = 10%

SP = Rs.216

CP = (SP x 100)/(100 - L%)

     = 21600/80

CP = Rs.270

Therefore,

  CP = Rs.270
