Question

find the loss or gain% if the cp of 10 articles all of the same kind is equal to sp of 8​

Answer 1

Answer:

C.P. of 10 articles = S.P. of 8 articles = ₹80 (suppose)

∴ C.P. of 1 article = 80/10

= ₹8

And S.P. of 1 article = 80/8

= ₹10

∴ Gain = S.P. – C.P.

= ₹10 - ₹8

= ₹2

Gain% = (Gain × 100)/C.P.

= (2 × 100)/8

= 25%
