Question

4. A trademan allows a discount of 25% on the M.P. How much above the C.P. must he mark his
articles to make a profit of 17%?​

Answer 1

This structured approach would be helpful :

Let CP = 100

MP = x

Discount = 15%

SP = 119

Profit = 19

Facts :

• MP is always marked up as a % of CP.
• Discount is always on MP
• MP - Discount = SP
• SP - CP = Profit

Plugging in values, x - 0.15x = 119

=> 0.85x = 119

=> x = 119/0.85 = 140

Markup = 40/100 x 100 = 40%

Note : There are five variables involved in this type of question. If these variables are written strictly in above order, and any four variables are known, it is easy to determine the fifth.

Answer 2

Step-by-step explanation:

Here, r =15% and R = 19%

Therefore, Required percentage

= (r+R100−r)×100(r+R100−r)×100%

= 15+19100−15×100%=34×10085%15+19100−15×100%=34×10085% = 40%
