Explanation:

Let the income of B be 100.
Income of A = 100 40/100 = 40
A’s income is equal to 70% of B’s expenditure so,
40 = 70% of B’s expenditure
Expenditure of B = \frac{40}{70} \times 100 = 57.14 = 400/7
Saving of B = 100 - 400/7 = 300/7
The expenditure of A is equal to 60%of B’s expenditure so,
Expenditure of A = 60% of B’s expenditure
Expenditure of A = 60x $_{7\times 100}^{400}$ = 240/7
Saving of A = 40 - 240/7 = 40/7
The ratio of the savings of A and B = 40/7 : 300/7 = 2 : 15
