Question

8) Suraj sells goods at a discount of 10% and stills makes a profit of 5%. By how much percent had
he marked-up the price of the goods?​

Answer 1

Answer:

Step-by-step explanation:

Let CP be x

Discount = 10%

So, SP will be = x - (10/ 100 × x)

= x - x/10

= (10x - x) /10

= 9x / 10

Now, Profit = 5%

So SP = CP + (5% of CP)

= x + (5/100 × x)

= x + x/20

= (20x + x)/20

= 21x/20

So, % of Marked price =

= {(9x/10) / (21x/20)} ×100%

= {9x × 20/ 21x × 10} × 100%

= 2/3 × 100%

= 66.67%
