Solution

The correct option is C $\frac{7}{6}$
$γ_{r} = γ_{a} + γ_{g}$
$7 γ_{g} = γ_{a} + γ_{g}$
$∴ γ_{a} = 6 γ_{g}$
$∴ \frac{γ_{r}}{γ_{a}} = \frac{7}{6}$

The correct option is C 76γr=γa+γg7γg=γa+γg∴γa=6γg∴γrγa=76

The correct option is C $\frac{7}{6}$
$γ_{r} = γ_{a} + γ_{g}$
$7 γ_{g} = γ_{a} + γ_{g}$
$∴ γ_{a} = 6 γ_{g}$
$∴ \frac{γ_{r}}{γ_{a}} = \frac{7}{6}$
