Question

the cost price of 32 articles is equal to the selling price of two dozen of them.
find the gain or loss percent

Answer 1

LET THE CP OF 1 ARTICLE=100
i.e. CP OF 32 ARTICLES=3200
i.e. SP OF 24 ARTICLES=3200
i.e. SP OF 32 ARTICLES=3200x32/24=12800/3
i.e. PROFIT=(12800/3)-3200=3200/3
i.e. PROFIT %=(3200/3)(100)/3200=100/3=33.3%

Answer 2

loss
loss%= 32x - 24x÷32x × 100
= 8x÷32x × 100
=25%
loss%= 25%
