Question

the cost price of 10 articles is equal to sp of 9 articles
find gain percent ​

Answer 1

Answer:

CP of 10 articles= SP of 9 articles

= 10*9

=90

CP of 1 article=90/10

= 9

SP of 9 articles=CP of 10 articles

= 9*10

= 90

SP of 1 article =90/9

=10

since,Sp>CP, so its gain

Profit = sp-cp

10-9

=1

Profit%= (profit/CP)*100

= (1/9)*100

=11.11%
