Let x be the total number of people who could have voted. We know that 4/25 didn't vote, so the actual number of people who voted is the remaining 21/25 of x.

Out of these people, 4/7 voted for the winner:


(21)/(25)x\cdot(4)/(7)=(12)/(25)x

We know that this fraction resulted in 4956 votes, solving for x we have


x=(4956\cdot 25)/(12)=10325

So, 10325 people could have voted. But we know that 4/25 didn't vote, while the remaining 21/25 did. So, the number of voters who took part to the election is


10325\cdot 21/25=8673

Just for checking, we have indeed


8673\cdot (4)/(7)=4956

which confirms the result.
