Answer 1

Step-by-step explanation:

let cp =rs 100

mp= cp+ 20/100×100

=120

d% = 10%

sp= 100- 10

----‐--------- × mp

100

= 90

--------- ×120

100

= 108

gain = sp-cp

= 108- 100

=8

g %= 8%

Answer 2

Answer:8%

Step-by-step explanation:

Let the cp be x

Hence the mp will become 120x/100

:.the resulting sp will be 120x * 90/10000

=108x/100

Hence the total gain = 8x/100

Which = 8% gain
