Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 51%.
Explanation:
Let the total number of registered voters be 100.
Now, supporters of P = 70% of 100 = 70
So, supporters of Q = 100 - 70 = 30
Expected voters for P = 60% of 70 + 30% of 30 = 42 + 9 = 51
The percentage of registered voters which are expected to vote for candidate P = = 51%
Hence the percentage of the registered voters are expected to vote for candidate P is 51%.
