Question

two article are sold for tha same price, on tha first the lose was 20%, what should be tha profit percentage on the second , so that on tha whole there will be no gain nor lose​

Answer 1

first article

let cp1 =100

loss = 20%

sp1 = 100-20 =80

second article

sp2 =sp1= 80

cp2 = 80/(1+g%)

total cp = cp1+cp2 =100+cp2

total sp = sp1+sp2 =160

sp-cp =0

sp=cp

160= 100+cp2

cp2 = 60

80/1+g% =60

1+g% = 80/60 =4/3 =1+1/3

g% =1/3

g% =1/3×100 =33⅓%
