Answer 1

Answer:

30%

Step-by-step explanation:

MP = 100

d% = 10%

d = d% of MP = 10% 0f 100 = 10

SP = MP - d = 100 - 10 = 90

P% = 17%

CP = SP × 100/(100+P%)

CP = 90 × 100/117 = 1000/13

now...x = MP - CP = 100 - 1000/13 = 300/13

x% = x × 100 / CP

x% = 300 × 100 × 13 / ( 13 × 1000 )

x% = 30%
