Answer 1

Answer:

Step-by-step explanation:

Let CP = 100

SP = Rs. 105

Discount(d) = 10 %

We have,  

SP=  

100

MP(100−d)

​  

 

MP=  

100−10

105×100

​  

=  

90

105×100

​  

=

350

​  

 

MP−CP=

Answer 2

Step-by-step explanation:

Let MP= x

CP= 2000

SP= CP+12% of 2000

= 2000+ 240

=Rs. 2240

SP= MP - 12% of MP

=x- 20% of x

= x - 0.20 x

= 0.80x

0.80x = 2240

x = 2800

MP = Rs. 2800
