Question

if the selling price of an article is 4/5 th if it's cost price, find the loss persent​

Answer 1

Explanation:

let, the s.p of an article=100/-

4/5th of s.p = 4/5*100 = 80/-

% loss= cp-sp/cp * 100

100–28= x-80/x *100

by solving you will get x= 8000/27 which can be further simplified as 1000/9

i.e cp= x = 1000/9

now, sp = 6/5 * 100 = 120/-

%p= sp-cp/cp * 100

%p= 120 - 8000/27 / 8000/27 * 100

solving above equation

%p = 8%
