Question

if the selling price 6 articles is equal to the cost of 9 articles then find the gain or loss percent​

Answer 1

Answer:

sp of 6 articles = x = cp of 9 articles

sp of 1 article = x/6

cp of 1 article = x/9

gain or loss = x/6 - x/9

=3x-2x/18

=x/18

gain or loss % = gain or loss / cp ×100

= x/18/x/9 ×100

=x/18 × 9/x ×100

=50%
