Question

Rahim purchased a watch at 20% discount on its marked price, but sold it at the marked price.find the gain percent of Rahim on this transaction.​

Answer 1

Answer:

25%

Step-by-step explanation:

Let marked price be 100

Raheem purchased it at 20% discount

So CP of Raheem =100-20=80

Raheem sold it for marked price i.e. 100

total profit earned by Raheem= 100-80=20

So gain percent=

$\frac{total \: gain \times 100}{cp}$

$\frac{20 \times 100}{80}$

=25%
