Question

the ratio of the income of two workers A and B in an office is 3 : 2. if they spend 20% and 25% of their income respectively, find the percentage of their saving?

Answer 1

Answer:

Ratio of saving of A and B = 8:5

Step-by-step explanation:

Let the income of A = X

Ration of income of A and B = 3:2

∴ Income of B = 2/3X

A spend 20% of his income.

∴ Saving of A = Income - Spending

∴ Saving of A = X - 20% of X = 0.8X ..... (1)

∴ % Saving of A = 80%

B spends 25% of his income.

∴ Saving of B = Income - Spending = 75% of (2/3)X =

∴ Saving of B = 0.75 × 2/3 X

∴ Saving of B = 0.5 X ...(2)

∴ % saving of B = 75%

Ratio of savings of A and B = 0.8X : 0.5X

∴ Ratio of saving of A and B = 8:5
