Question

. By selling a fan for Rs. 720, a trader losses 20%, find loss amount and cost
price​

Answer 1

Answer:

180

Step-by-step explanation:

sp=720

L%=20

let's say cp=100

so:

L%=(L/cp)×100

20=(L/100)×100

L=100

then new sp will be:

100-20=80 which is sp

so if sp is 80 then cp is=100

if sp is 1 then cp=100/80

if sp is 720 then cp= (100/80)720

=》900

so cp=900

and

loss amount=900-720=180
