Question

the sp of an artice is 5/4 of cp . what is the loss percentage

Answer 1

Hey there! ☺☻☺

S.P of an article = 5/4 of it's C.P
Let the C.P be 100.

ATQ,
S.P = 5/4 x 100
S.P = 5 x 25
S.P = 125

Loss  = S.P  - C.P
          = 125 - 100
          = ₹ 25
Now, 
Loss% = loss/C.P * 100
            = 25/100 * 100
            = 25%

Hope It Helps You! ☺☻☺
