GATE Civil Engineering (CE) 2018 Shift 1 Solved Paper

The temperature $\mathit{T}$ in a room varies as a function of the outside temperature ${\mathit{T}}_0$ and the number of persons in the room $\mathit{p}$, according to the relation $\mathit{T}=\mathit{K}\left(\mathit{\theta }\mathit{p}+{\mathit{T}}_0\right)$, where $\mathit{\theta }$ is $\mathit{K}$ are constants. What would be the value of $\mathit{\theta }$ given the following data?

${\mathit{T}}_0$	p	T
25	2	32.4
30	5	42.0
