Let TF be temperature on Fahrenheit scale corresponding to 60° C on Celsius scale. Then (60-0/100-0) = (TF -32/212 -32) (3/5) = (TF - 32/180) 5TF - 160 = 540 5TF = 700 or TF = (700/5)°F = 140° F

Q. The temperature of an object is $6 0^{\circ} C$ . Its value in Fahrenheit scale is

$12 0^{\circ}$ F

$13 0^{\circ}$ F

$14 0^{\circ}$ F

$11 0^{\circ}$ F

Let $T_{F}$ be temperature on Fahrenheit scale corresponding to $6 0^{\circ} C$ on Celsius scale. Then
$\frac{60 - 0}{100 - 0} = \frac{T _{F} - 32}{212 - 32}$
$\frac{3}{5} = \frac{T _{F} - 32}{180}$
$5 T_{F} - 160 = 540$
$5 T_{F} = 700$ or $T_{F} = \frac{700}{5}^{\circ} F = 14 0^{\circ} F$
