Question

An item was sold four fifths of its cost pric Find the profit or loss per cent in the transaction.
Pls explain with the process.

Answer 1

Answer:

Cost price =4/5 SP

SP =5/4 CP

gain% =(Sp--CP)×100/CP

=(5/4CP --CP)×100/CP

=CP(5/4--1)×100/CP

1/4× 100 = 25%

Method 2

Let SP be 100

CP =4/5 ×100 =80 Rs

Gain %= (SP -- CP)×100/CP

=(100--80)×100/80

=20×100/80 = 25 %
