​

Answer 1

Answer:

5percent

Step-by-step explanation:

Assumption

\textbf{\underline{Cost\;Price\;of\;Article}}

CostPriceofArticle

= 100n

\textbf{\underline{Marked\;40\;Percent\;above\;its\;cost\;price}}

Marked40Percentaboveitscostprice

{\boxed{\sf\:{Marked\;Price}}}

MarkedPrice

\tt{\rightarrow 100n+\dfrac{40}{100}\times 100n}→100n+

100

40

×100n

= 140n

\textbf{\underline{Price\;and\;discount\;of\;25\;Percent}}

Priceanddiscountof25Percent

Now,

Discount = 25℅

\tt{\rightarrow\dfrac{25}{100}\times 140n}→

100

25

×140n

= 35n

\textbf{\underline{Selling\;Price}}

SellingPrice

{\boxed{\sf\:{Marked\;Price-Discount}}}

MarkedPrice−Discount

= 140n - 35n

= 105n

{\boxed{\sf\:{Gain}}}

Gain

= 105n - 100n

= 5n

{\boxed{\sf\:{Gain\;Percentage}}}

GainPercentage

\tt{\rightarrow\dfrac{5n}{100n}\times 100}→

100n

5n

×100

= 5%
