Answer : [C]
Explanation :
|
|
|
Let
the number of persons eligible to vote be x.
|
|
|
|
Then,
voters who voted for A = 30% of x.
|
|
|
|
Voters
who voted for B = 60% of (70% of x).
|
|
|
|
|
=
|
|
|
x
|
|
x
100
|
|
%
of x = 42% of x.
|
|
|
|
|
|
Voters
who did not vote = [100 – (30 + 42)]% of x = 28% of x.
|
|
|
|
|
30%
of x - 28% of x = 1200
|
|
|
2%
of x = 1200
|
|
x =
|
|
|
|
= 60000.
