Two candidates P and Q contested in an election. 70% of the registered voters are P supporters. If 60% of the P supporters and 30% of the Q supporters are expected to vote for candidate P, then what percentage of the registered voters are expected to vote for candidate P?
Answer & explanation
Correct answer: option 2
Let total voters be 1000
Then 700 are P supporters and 300 are Q supporters
Total votes to P
= 60% of 700 + 30% of 300
= 420 + 90
= 510
Percentage of P voters
= 510 × 100/1000
= 51 %
