Question

A dealer marks his goods at 35% above the cost price allow a discount of 20% on the marked price. find his gain or loss percent ​

Answer 1

Answer:

8% gain

Step-by-step explanation:

Let C be the cost price.

Let M be the marked price.

Let S be the final selling (discounted) price.

The dealer marks goods at 35% above cost price

=> M = C + 35% of C

       = C + 0.35 C

       = ( 1 + 0.35 ) C

       = 1.35 C

The dealer allows a discount of 20%

=> S = M - 20% of M

      = M - 0.2 M

      = ( 1 - 0.2 ) M

      = 0.8 M

      = 0.8 × 1.35 C

      = 1.08 C

      = C + 8% of C

So the dealer has made an 8% gain
