Sure, let's solve this step by step:

1. Let's denote A's salary as 'a' and B's salary as 'b'. According to the problem, a + b = 14,000.

2. A spends 80% of his salary, so he saves 20%. Therefore, A's savings are 0.2a.

3. B spends 85% of his salary, so he saves 15%. Therefore, B's savings are 0.15b.

4. The problem states that their savings are equal, so 0.2a = 0.15b.

5. We can solve this system of equations either by substitution or by elimination. Let's use substitution:

From a + b = 14,000, we can express a as a = 14,000 - b.

6. Substitute a in the equation 0.2a = 0.15b:

0.2(14,000 - b) = 0.15b
2,800 - 0.2b = 0.15b
2,800 = 0.35b
b = 2,800 / 0.35
b = 8,000

So, B's salary is Rs. 8,000.
