A and B spend 60% and 75% of their incomes, respectively. If the savings of A are 20% more than that of B. then by what percentage is the income of A less than the income of B?
Let the income of A and B be X and Y respectively.Â
Saving of A = X - $$\frac{60}{100} \times$$ X = 0.4X
Saving of B = Y - $$\frac{75}{100} \times$$ Y = 0.25Y
If the savings of A are 20% more than that of B then,
Saving of A = 0.25Y $$\times \frac{120}{100} = 3Y/10
0.4X = 3Y/10
4X = 3Y
Ratio of income of A and B = 3 : 4
Required percentage = $$\frac{(4 - 3)}{4} \times$$ 100 = 25%
