Answer 2

Answer:

Their ratio of sum of income to their sum of savings is 5 : 3.

Step-by-step explanation:

Given:

Ratio of income of a : b = 2 : 3

Sum of their expenditure = Rs. 8000

Amount of saving of a = Amount of Expenditure of b.

To find: Ratio of their sum of Income to sum of saving.

let the ratio of the expenditure of a and b =  1 : 1

Total Expenditure = 2

⇒ 2 unit = 8000

1 unit = 4000

Saving ratio of the a : b = 2 - 1 : 3 - 1 : = 1 : 2

Total Ratio of income of a and b = 2 + 3 = 5

Total Ratio of Saving of a and b = 1 + 2 = 3

Ratio of sum of their income to sum of their saving = 5 : 3

Therefore, Their ratio of sum of income to their sum of savings is 5 : 3.
