Question

If SP of 12 articles is cost price of 10 articles, find the gain/loss percentage.​

Answer 1

$\large\underline\blue{\bold{Solution:-  }}$

Let cp of an article = Rs 1

Cp of 10 articles = Rs 10

Sp of 12 articles = cp of 10 articles

⟹ Sp of 12 articles = Rs 10

∴ Sp of 1 article = Rs 10/12 = Rs 5/6

Clearly 5/6 < 1 i.e, Sp < Cp

⟹ Loss = Cp - Sp

= rs ( 1 - 5/6) = Rs 1/6

⟹ Loss ℅ = Loss/Cp× 100

= 1/6 × 100 = 50/3%

= 16.67% .

∴ Loss % = 16.67% .
