Question

ratio of income of A and B is 3:4 and their expenditure is 5:6, who save more between A and B

Answer 1

Hello Dear.


Given ⇒
Ratio between the Income of A and B = 3 : 4
Ratio between the Expenditure of A and B = 5 : 6

Let the Income of the A and B be 3x and 4x respectively. Also, Let the Expenditure of the A and B be 5y and 6y respectively.

For A,
Saving = Income - Expenditure.
= 3x - 5y.

For B,
Saving = Income - Expenditure.
= 4x - 6y.


For Finding, you can take the x as Rs. 100 and y as Rs. 50. [It is just an example]

Now, A's Income = 3x - 5y
= 3(100) - 5(50)
= 300 - 250
= Rs. 50

B's Income = 4x - 6y
 = 4(100) - 6(50)
 = 400 - 300
 = Rs. 100

From this we can see that B's saving is more than the A's saving. For any values of x and y, B's Saving is always more than the A's saving.



Hope it helps.

Answer 2

Answer:

For A,

Saving = Income - Expenditure.

= 3x - 5y.

For B,

Saving = Income - Expenditure.

= 4x - 6y.

For Finding, you can take the x as Rs. 100 and y as Rs. 50. [It is just an example]

Now, A's Income = 3x - 5y

= 3(100) - 5(50)

= 300 - 250

= Rs. 50

B's Income = 4x - 6y

 = 4(100) - 6(50)

 = 400 - 300

 = Rs. 100
