Question

100/105x (350) = 100/100x ( 340 )​

Answer 1

Answer:

=> 105x/100 – 3x/100 =80

=> (105x - 3x)/100 = 80

=> 102x/100 = 80

=> 51x/50 = 80

=> 51x = 80×50

=> x = 4000/51 answer

Answer 2

$\begin{gathered}\\ \sf\longmapsto \frac{100}{105x}(350)=\frac{100}{100x}(340)\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto \frac{20}{21x}×350=\frac{1}{x}×340\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto \frac{20}{3x}×50=\frac{340}{x}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto \frac{1000}{3x}=\frac{340}{x}\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 1000x=1020x\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto 1000x-1020x=0\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto -20x=0\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto x=0\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto x∈Ø\end{gathered}$
