Let's denote A's salary as 'a' and B's salary as 'b'.

From the problem, we know that:

a + b = 14000 (since their combined salary is Rs. 14,000)

We also know that A spends 80% of his salary and B spends 85% of his salary, and their savings are equal. This means that:

a * (1 - 0.80) = b * (1 - 0.85)

Solving this equation gives us:

a * 0.20 = b * 0.15

We can simplify this to:

a/b = 0.15/0.20 = 0.75

Now we have a system of two equations:

a + b = 14000
a/b = 0.75

We can solve this system of equations to find the values of 'a' and 'b'.

First, let's express 'a' in terms of 'b' using the second equation:

a = 0.75b

Now we can substitute this into the first equation:

0.75b + b = 14000
1.75b = 14000
b = 14000 / 1.75
b = 8000

So, B's salary is Rs. 8000.
