Q: The graph between two temperature scale A and B is shown in figure between upper fixed point and lower fixed point there are 150 equal division on scale A and 100 on scale B. the relationship for conversion between the two scales is given by

Numerical

(a) $\frac{t_A – 180}{100} = \frac{t_B}{150} $

(b) $\frac{t_A – 30}{150} = \frac{t_B}{100} $

(c) $\frac{t_B – 180}{150} = \frac{t_A}{100} $

(d) $\frac{t_B – 40}{100} = \frac{t_A}{180} $

Ans: (b)
