If $(x+1): 8=3.75: 7$, then the value of $x$ is
(a)$1 \frac{2}{7}$
(b)$2 \frac{2}{7}$
(c)$3 \frac{2}{7}$
(d)$4 \frac{2}{7}$
Answer
Answer (as printed): C
Explanation
$(x+1): 8=3.75: 7 \Leftrightarrow 7(x+1)=8 \times 3.75=30$ $\Leftrightarrow x+1=\frac{30}{7} \Leftrightarrow x=\frac{30}{7}-1=\frac{23}{7}=3 \frac{2}{7}$.
