darshan prajapati  (11 years ago)

it is b)20
assume article has value 100 rs
as article was marked 20% above cost,it becomes 120 rs
after allowing 1st 10% discount it becomes 120-12=108
if we take x=20 then it becomes 108-20% of 108=108-21.6=86.4
so 100-86.4=13.6% loss is obtained

let the CP=100
MP=120
after first discount it will be 120-(10%of 120)
=120-12
=108
x% x%
108------------->(100-13.6)===>108------------->86.4
10% of 108=10.8
20% of 108= 2*10.8=21.6
therefore 20
