Question

If $\frac{(x+0.7x)}{2}=0.85$, then the value of $x$ is:

• A. $2$
• B. $1$
• C. $-1$
• D. $0$

Answer 1

The correct option is B $1$

Given, $\frac{x+0.7x}{2}=0.85$

Multiply $2$ on both the sides,

$\Rightarrow x+0.7x=1.7$

$\Rightarrow 1.7x=1.7$

Divide both sides by $1.7$, we get

$\Rightarrow x=1$
