# On a new scale of temperature ( which is linear ) and called the W scale the freezing and boiling points of water are $39^{\circ}W \: and \: 239^{\circ} W$ respectively. What will be the temperature on the new scale, corresponding to a temperature of $39^{\circ}$C on the Celcius scale ?

$\begin {array} {1 1} (1)\;139^{\circ}W & \quad (2)\;78^{\circ}W \\ (3)\;117^{\circ}W & \quad (4)\;200^{\circ}W \end {array}$
