For some non-zero real values of $a, b$ and $c$, it is given that $\left|\frac{c}{a}\right|=4,\left|\frac{a}{b}\right|=\frac{1}{3}$ and $\frac{b}{c}=-\frac{3}{4}$. If $a c>0$, then $\left(\frac{b+c}{a}\right)$ equals

Accepted Answer

A - 1. ac>0 so c/a=4, c=4a; b=-(3/4)c=-3a (consistent with |a/b|=1/3). (b+c)/a = (-3a+4a)/a = 1.
