we can use the given ratio to find the expenditure and then subtract it from the income to find the savings.

income : expenditure = 3 : 2

first, let's find the expenditure:
expenditure = income × (2/3) = 21000 × (2/3) = 14000

now, let's find the savings:
savings = income - expenditure = 21000 - 14000 = 7000

so, the correct option is b) 7000.
