Wealth effect is such that $10 change in wealth produces $1 change in consumption at each level of income.
A $160 decrease in wealth will decrease the consumption by $16 at each level of income.
(A) initially at $680 level of income, consumption was $648. After the wealth decrease by $160 the consumption will fall by $16.
So, the new level of consumption at $680 income is $632.
I.e., new consumption = $648 - $16 = $632.
(B) new level of saving = $680 - $632.
New level of saving = $48.
