Answer
15 votes
Solution
Hanako has to obtain votes more than Jiro who got votes most at present to be elected. Remaining number of votes is 45 - 20 = 25 votes.
Hanako needs 9 - 5 = 4 votes to catch up with Jiro.
Remaining number of votes is 25 - 4 =21 votes.
Hanako should obtain 10 + 1 = 11 votes among 21 votes according to calculation of 21/2 = 10 with remainder 1.
Therefore the number of votes to find is 4 + 11 = 15 votes.
