Solution:

We are given that;

Total Votes =7500

Invalid Votes =20% Of 7500

\Rightarrow Invalid Votes = \frac{20}{100} \times 7500

\Rightarrow Invalid Votes =1500

\Rightarrow Valid Votes =7500-1500=6000

So, the valid votes were 6000.

Let there be two candidates A and B. Suppose A gets 55% of valid votes i-e;

A's Votes =55% of 6000

\Rightarrow A's Votes =\frac{55}{100}\times 6000

\Rightarrow A's Votes =3300

So,  A got 3300 of valid votes, remaining votes will have gone to candidate B;

\Rightarrow B's Votes =6000-3300=2700

So, the other candidate (B) got 2700 votes
