<em></em>
Answer:
gain percent = 25%
Step-by-step explanation:
To solve the question given, we will follow the steps below:
gain% = × 100%
But from the question;
"CP of 15 articles equals to the SP of 12 articles", this implies that
15 c.p = 12 s.p
s.p = 15c.p / 12
s.p = =
s.p =
substitute s.p = into the formula
gain% = × 100%
= × 100%
= × 100%
= ÷ c.p × 100%
= ×
× 100%
= × 100%
= 25 %
