Mathematics

Answer:

Step-by-step explanation:

Here are the steps to follow when solving absolute value inequalities:

Isolate the absolute value expression on the left side of the inequality.

If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions.

If your problem has a greater than sign (your problem now says that an absolute value is greater than a number), then set up an "or" compound inequality that looks like this:

(quantity inside absolute value) < -(number on other side)

OR

(quantity inside absolute value) > (number on other side)

The same setup is used for a ³ sign.

If your absolute value is less than a number, then set up a three-part compound inequality that looks like this:

-(number on other side) < (quantity inside absolute value) < (number on other side)

The same setup is used for a £ sign

Q). If the selling price of 10 mangoes is equal to the cost price of 12 mangoes, find the profit percentage.​
lianna [129]

Step-by-step explanation:

Here :-

  • Selling price of 10 mangoes is equal to the cost price of 12 mangoes

\begin{gathered}\end{gathered}

Let the cost price of one mango be ₹1. So :-

  • Cost Price of 10 mangoes = ₹10
  • Selling Price of 10 mangoes = ₹12

↝ Here the selling price of 10 mangoes is equal to the cost price of 12 mangoes. It means selling price of 10 mangoes = cost price of 12 mangoes. So, the selling price of 12 mangoes is ₹12 and the cost price of 10 mangoes is ₹10.

  • Profit = S.P > C.P

\begin{gathered}\end{gathered}

<em>Fistly, finding the profit :-</em>

{\dashrightarrow\sf{Profit = Selling \:  Price  - Cost \:  Price}}

{\dashrightarrow\sf{Profit = 12 - 10}}

{\dashrightarrow{\sf{\underline{\red{Profit = Rs.2}}}}}

∴ The profitis Rs.2.

\begin{gathered}\end{gathered}

<em>Now, finding the profit percentage :-</em>

\dashrightarrow{{\sf{Profit \: \%= \dfrac{Profit }{Cost \: Price} \times 100}}}

\dashrightarrow{{\sf{Profit \: \%= \dfrac{2 }{10} \times 100}}}

\dashrightarrow{{\sf{Profit \: \%= \dfrac{2 \times 100 }{10}}}}

\dashrightarrow{{\sf{Profit \: \%= \dfrac{200 }{10}}}}

\dashrightarrow{{\sf{Profit \: \% =  \cancel\dfrac{200 }{10}}}}

{\dashrightarrow{\sf{\underline{\red{Profit \: \% =  20 \: \%}}}}}

∴ The profit percent is 20%.
