Answer 1

Answer:

Cost are $1 and $1.5

Step-by-step explanation:

Let the cost of pipe sold on profit be x

Let the cost of pipe sold on loss be y

Given

$1.20 = x \times 1.2$

$x = \frac{1.2}{1.2} = 1$

Also

$1.20 = y \times .8$

$y = \frac{1.2}{.8} = 1.5$

$\huge\red{\underline{{\bf Answer : }}}$

$\large\bf{\underline\blue{Solution:-}}$

• For 1st pipes,

• SP (selling price) = 1.20

• Profit = 20%

$\large{\boxed{{\bf\pink{CP\: = SP\: - \: profit. }}}}$

$\sf\green{⟼CP = 1.20 - 20\% \times CP}$

$\sf\green{⟼120\%CP =1. 20}$

$\sf\green{⟼CP = \frac{1.20}{120} \times 100}$

$\sf\green{⟼CP _{1} = 1.00}$

$\large{\boxed{{\bf\pink{ For\: 2nd=s.p + loss}}}}$

$\sf\green{⟼CP = 1.20 + 200\%CP}$

$\sf\green{⟼80\%CP = 1.20}$

$\sf\green{⟼CP=\frac{1.20}{80}\times 100 = 1.50}$

$\sf\green{⟼Total\:CP = 1.00+1.50 = 2.50}$

$\sf\green{⟼Total\:SP = 1.20 + 1.20 = 2.40 }$

• He suffered 10 paise loss.
