Question

if the selling price of 20 articles is equal to the cost price of 15 articles then what is the loss percent​

Answer 1

LET SP OF 20 ARTICLES=X

SP OF 1 ARTICLE=X/20

LET CP OF 15 ARTICLES= X

SP OF 1 ARTICLE=X/15

LOSS= CP-SP

=X/15- X/20

=X/60

LOSS%= LOSS/CP ×100

=(X/60)/(X/15)×100

= 15%
