In a student council election, there were three contestants. All the voters participated in the voting and 10% of votes were declared invalid. The contestants got the votes in the ratio 8 : 7 : 5. If the second candidate in the list got 4725 votes, the total number of valid votes is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 13500.
Let the total number of valid votes = x
The vote ratio is 8 : 7 : 5, so the total parts = 8 + 7 + 5 = 20 parts.
The second candidate got 7 parts of the valid votes = 7/20 × x = 4725
x = (4725 × 20)/7 = 94500/7 =13,500
