The graph between two temperature scales P and Q is shown in the figure. Between upper fixed point and lower fixed point there are 150 equal divisions of scale P and 100 divisions on scale Q. The relationship for conversion between the two scales is given by :-

JEE Main 2023 (Online) 25th January Evening Shift Physics - Heat and Thermodynamics Question 165 English

$${{{t_P}} \over {100}} = {{{t_Q} - 180} \over {150}}$$

$${{{t_P}} \over {180}} - {{{t_Q} - 40} \over {100}}$$

$${{{t_Q}} \over {150}} = {{{t_P} - 180} \over {100}}$$

$${{{t_Q}} \over {100}} = {{{t_P} - 30} \over {150}}$$
