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

The Celsius scale of temperature can be converted to Fahrenheit scale using the relationship $F = 1.8C + 32$, where $F$ and $C$ are temperature recorded in degrees Fahrenheit and Celsius, respectively. Ajay noted down the temperature of a chemical reaction as $x$ degrees Fahrenheit but reported it as $x$ degrees Celsius by mistake. If this led to a recording of the temperature that was 144% higher than the actual temperature in Celsius scale, then $x$ equals ___
