Explanation:

Let the total number of vote = 1
Number of invalid votes= 1/6
Then number of valid votes= 1- (1/6)=5/6
‘A’ got 8/15 of valid votes
then ‘B’ should have 7/15 of valid votes
Number of votes ‘B’ got=7/15 * 5/8=4900(GIVEN)
Then value of 1= 12,600 which is equal to the total number of votes
