Which number gives the same result when added to $1 \frac{1}{2}$ and when multiplied by $1 \frac{1}{2}$ ?
(a)1
(b)3
(c)5
(d)7
Answer
Answer (as printed): B
Explanation
Let the required number be $x$. Then, $x+1 \frac{1}{2}=x \times 1 \frac{1}{2} \Rightarrow x+\frac{3}{2}=\frac{3}{2} x \Rightarrow \frac{x}{2}=\frac{3}{2} \Rightarrow x=3$.
