Answer 1

Answer

Rs 1000

Step-by-step explanation:

selling price of article = rs 800

loss% = 20%

CP =RS ( SP*100/100-LOSS%)

     =RS (800*100/100-20)

     =RS (80000/80)

     = RS 1000

Answer 2

Answer:

cp = Rs.1000

Step-by-step explanation:

l =  l% * cp /100

= 20% * cp /100

 = cp / 5

cp = sp + l

    = 800 + cp /5

 4/5 cp  =  800

= cp = Rs.1000
