Answer 1

Answer:

Number of voters who didn't cast their votes

= 2000

Step-by-step explanation:

Votes secured by A = 65%

Votes secured by B = 35%

Suppose the number of votes secured by B are "x"

Votes secured by A = x + 1920

65% = x + 1920

Subtract the number of votes secured by B

65% - 35% = (x+1920) - (x)

30% = 1920

Total number of valid votes = 1920 / 30% = 6400

Total votes casted = Valid votes + Invalid votes

= 6400 + 1600 = 8000

80% people casted their votes

People eligible to vote = 8000 / 80% = 10000

Thus people who didn't cast their vote

= 10000 x 20% = 2000
