Step-by-step explanation:
Let the total number of voters be x.
As 10% of the voters did not cast their votes
Then, Votes polled =90% of x.
10% of the votes polled were found invalid
Valid votes =90% of (90% of x).
54% of [90% of (90% of x)]−46% of [90% of (90% of x)]=1620
=>8% of [90% of (90% of x)]=1620
⇒1008×10090×10090×x=1620
⇒x=(8×90×901620×100×100×100)=25000
