Answer:

The dealer should mark his goods at 13.33 per cent more than the list price.

Step-by-step explanation:

LP = List Price

CP = Cost Price

MP = Marked Price

SP = Selling Price

Discount (%) = 20

Profit (%) = 10

Cost Price is 15 per cent off the list price

=> CP is 15% lower than LP

=> CP = LP - 15% of LP

=> CP = LP - 0.15*LP

=> CP = 0.85*LP ............(i)

He needs to make a profit of 20%

=> His selling price has to be 20% more than his cost price

=> SP = 20% more than CP

=> SP = CP + 20% of CP

=> SP = CP + 0.2*CP

=> SP = 1.2*CP .........(ii)

He allows a discount of 10 per cent

=> His selling price is 10 per cent lower than marked price

=> SP = 10% lower than MP

=> SP = MP - 10% of MP

=> SP = MP - 0.1*MP

=> SP = 0.9*MP

=> MP = (1/0.9)*SP ...........(iii)

From (iii), we get:

MP = (1/0.9)*SP

But SP = 1.2*CP ...from (ii)

=> MP = (1/0.9)*1.2*CP

But CP = 0.85*LP ....from (i)

=> MP = (1/0.9)*1.2*0.85*LP

=> MP = [(1.2*0.85)/0.9]*LP

=> MP = 1.1333*LP

=> MP = LP + 0.1333*LP

=> MP = LP + (13.33/100)*LP

=> MP = LP + 13.33% of LP

=> MP is 13.33% more than LP

The dealer should mark his goods at 13.33 per cent more than the list price.

Verification:

Let LP = 100 then MP = 13.33% more than 100 = 113.33

SP = 10% discount over MP = 0.9*MP = 0.9*113.33 = 102

CP = 15% lower than LP = 0.85*LP = 0.85*100 = 85

Profit = SP - CP = 102 - 85 = 17

Profit% = 100*(Profit/CP) = 100*(17/85) = 100*(1/5) = 100/5 = 20

He makes a profit of 20 per cent, as given. ......hence, verified.

Answer:

13.33% the MP should be above the LP to gain 20% gain.

Step-by-step explanation:

List price = LP

Marked price = MP

Selling price = SP

Now let's solve the sum

Let LP be x

Then CP ( discount = 15%)

= x-15x/100

=85x/100

=17x/100

Now

Dealers CP = 17x/100

Dealers SP ( if 20% gain required)

=120/100*17x/20

=6/5*17x/20

=51x/50

Dealers MP ( if 10% discount is offered)

=(100*SP) / (100— discount %)

=(100*51x/50) / 100-10

=51x/50

Therefore,

%above the LP is the MP

= (LP-MP/MP)*100

=(51x/50-x/x)*100

=120/9

=13.3333%

Felling happy after solving the sum.
