Question

on a new scale of temperature (which is linear)and caled the W scale .the freezing and boiling points of water are 39 degree W and 239 degree W respctvly .wahat will be the temperature on new scale corresponding to a temperature of 39 degree C on celsius scale 1)200 degree w 2)139 degree w 3)78 degree W 4)117 degree W

Answer 1

In the new scale 0 degree C is 39 degree w and 100 degree C is 139 degree w
.
so, value in degree w = value in degree C + 39 , so degree w = 39 + 39 = 78 degree w (option 3)
