Question

Three more than twice a integer is equal to $4$. What is the integer?

• A. $0.2$
• B. $0.3$
• C. $0.4$
• D. $0.5$

Answer 1

The correct option is D $0.5$

Let the number be ${}^{\prime }{n}^{\prime }$

Twice the number gives ${}^{\prime }2n^{\prime }$

Three more than twice the number is $2n+3$

Given that three more than twice the number $=$ $4$

$\Rightarrow 2n$ $+$ $3$ $=$ $4$

$\Rightarrow 2$ $\times$ $n$ $=$ $4$ $-$ $3$

$\Rightarrow n$ $=$ $\frac{1}{2}$

$\Rightarrow n$ $=$ $0.5$

Therefore, the number is $0.5$
