$Q10.$ Two models for Engel expenditure function are estimated.

Model I: $Y_t=1087\mathrm{.}930+0\mathrm{.}077x_t$

$q,t=(25\mathrm{.}58),(21\mathrm{.}64)$

$R^2=0\mathrm{.}350$

Model $II$: $Y_t=4005\mathrm{.}077-\frac{0\mathrm{.}3381}{x_t}$

$,t=(19\mathrm{.}259),(-20\mathrm{.}816)$

$R^2=0\mathrm{.}333$

where $=$ expenditure $on$ food $in$ rupees

$,=$ total expenditure $in$ rupees
