Question

the cost price of 12 mangoes is equal to selling price of 15 mangoes. find the loss percent?

Answer 1

C.P of 12 mangoes=S.P of 15 mangoes
S.P of 12 mangoes=C.P of 15 mangoes (C.P becomes S.P and S.P become C.P)

Let the price of each unit be Rs. 1

C.P>S.P =loss

loss=C.P-S.P
       =Rs.15-Rs12
       =Rs.3

loss%=loss/C.P*100
         =3/15*100
         =20%

Therefore answer=20%
      

Answer 2

 

loss % =  C.P -S.P / C.P * 100
           =  12 - 15/ 12 * 100
           =   3 / 12 * 100
           =  25 %
