Question

please give me answer
iska answer hi 22.4kg please solve equation ​

Answer 1

Given :

• Ratio of zinc and copper in alloy is 8:7

• Weight of zinc is 25.6 kg

To Find :

• Weight of the Copper in the alloy

Solution :

Let the weight of zinc be 8x and weight of copper be 7x

According to the Question :

$\longrightarrow \sf8x = 25.6 \: kg$

$\longrightarrow \sf \: x = \dfrac{25.6}{8} \: kg \:$

$\longrightarrow \sf \: x = 3.2\: kg \:$

Putting the value of x = 3.2 kg in the weight of copper.

$\longrightarrow \sf \: Copper = 7x$

$\longrightarrow \sf \: Copper = 7\times 3.2$

$\longrightarrow \sf \: Copper = 7\times 3.2$

$\longrightarrow \sf \: Copper = \large\boxed{ \sf \: 22.4 \: kg}$

Hence,Weight of Copper in the alloy is 22.4 kg

Answer 2

$\huge{\mathtt{\purple{Solution⇢}}}$

${\underline{\mathtt{GIVEN⇢}}}$

$\mathtt{⇢\: Ratio \: of \: zinc \: and \: copper \: is \: 8 \: : \: 7}$

$\mathtt{⇢\: Weight\: of \: zinc \: is \: 25.6\: kg}$

${\underline{\mathtt{To\: find\: ⇢}}}$

$\mathtt{⇢\: Weight \: of \: copper}$

_______________________

$\mathtt{⇢\:Let \:assume \:that \:weight \:of\: zinc\: = \:8x }$

$\mathtt{⇢\:Weight \:of \:copper\:=\: 7x}$

$\mathtt{⇢\: So \: zinc \:=\: 7x \:=\:25.6\: kg}$

$⇢ \: x = \frac{25.6}{8}$

$\mathtt{⇢\: x \:=\: 3.2 \: kg }$

$\mathtt{⇢\: Weight \:of \:copper \:will \:be:- }$

$⇢ \: \: 7 \times 3.2 = 22.4kg$

${\mathtt{\red{⇢\: copper \:=\: 22.4\: kg}}}$
