Let's denote the income of employees A, B, and C as IA, IB, and IC, respectively. Similarly, let's denote their expenses as EA, EB, and EC.

According to the given ratios: Income ratio = 1:2:3 Expenses ratio = 3:2:1

Now, let's calculate the savings for each employee:

Savings of A = IA - EA Savings of B = IB - EB Savings of C = IC - EC

Now, let's calculate the savings for each employee using the given ratios:

Income ratio = 1:2:3 Expenses ratio = 3:2:1

Let's assume that the common multiplier for both ratios is "x" (where x is a positive number).

So, the income for A, B, and C would be: IA = 1x IB = 2x IC = 3x

And the expenses for A, B, and C would be: EA = 3x EB = 2x EC = 1x

Now, let's calculate the savings for each employee:

Savings of A = IA - EA = (1x - 3x) = -2x Savings of B = IB - EB = (2x - 2x) = 0 Savings of C = IC - EC = (3x - 1x) = 2x

Now, let's order the employees in increasing order of the size of their savings:

1. Savings of A = -2x
2. Savings of B = 0
3. Savings of C = 2x

So, the correct order of employees in increasing order of the size of their savings is A > B > C.

The correct answer is A > B > C.
