Answer:i'm new here please help me

Step-by-step explanation:

cost of 10 compact disc=100

cost of 1 compact disc=10

sp. of 11 compact disc=100

sp. of one compact dis=100/11=9 1/11

Loss=IO-100/11=.(110-100) /11=10/11

Loss %=10/11x1/Iox loo=lox1x100/11x10

-=100/11=9 1/11%

OR

(11-10)/11 x loo=1 / 11 x loo=9 1/11%

Answer 2

Answer:

Let CP of a Compact Disc be x

CP of 11 Compact Disc = 11x

SP of 11 Compact Disc = CP of 10 Compact Disc = 10x

Loss = 11x - 10x = x

Loss% = x/11x × 100

= 100/11 % or 9 whole 1/11
