Question

X+X:0.1+X:0.2+X:0.25=192

 

Answer 1

X + X : 0,1 + X : 0,2 + X : 0,25 = 192

X + X x 10 + X x 5 + X x 4 = 192

X x (10 + 5 + 4) = 192

X x 19 = 192

X = 192 : 19

X = 192/19

Answer 2

X+X:0.1+X:0.2+X:0.25=192

X+X:1/10+X:1/5+X:1/4=192

X+X*10+X*5+X*4=192

X*(1+5+4+10)=192

X*20=192

X=192:20

X=9.6

Answer 3

\(x+\frac{x}{0.1}+\frac{x}{0.2}+\frac{x}{0.25}=192\)

\(\Leftrightarrow x+\frac{x}{\frac{1}{10}}+\frac{x}{\frac{2}{10}}+\frac{x}{\frac{25}{100}}=192\)

\(\Leftrightarrow x+10x+5x+4x=192\)

\(\Leftrightarrow20x=192\)

\(\Leftrightarrow x=\frac{192}{20}=\frac{48}{5}\)

Answer 4

X+X:0.1+X:0.2+X:0.25=192

X+X:1/10+X:1/5+X:1/4=192

X+X*10+X*5+X*4=192

X*(1+5+4+10)=192

X*20=192

X=192:20

X=9.6
