Question

The incomes of A and B is in the ratio 3:2. Their expenditures are 14000 and 10000. if A’s savings are 4000, what are B’s savings?

Answer 1

Let their income be 3x and 2x respectively.
Then, A's income = 3x
Expenditure + saving = total income
⇒14000+4000=3x
⇒x=6000
Now, Income of B= 2x
⇒2×6000
⇒12000
His savings= 12000 - 10000
⇒2000

Answer 2

incomes of A and B- 3:2
so incomes = 3x and 2x.
and their expenditures = 14000,10000.
A::::
expenditure+savings of A=total income.
14000+4000=3x.
18000=3x
x=18000/3.
so,x=6000.
B:::::
B's total income= 2x.
so 2x=2* 6000.
so B's income= 12000.
and B's savings=
total income-expenditure.
12000-10000=2000.
so B's savings are 2000.
