Question
In a mayoral election between two nominees, 20% of the
total votes were rejected as invalid. Out of the valid votes, 65% went to the winning candidate, who won by 1,920 votes. Find the number of valid votes.Solution
Let the number of votes be '100n' Number of valid votes = 0.8 X 100n = '80n' Number of valid votes received by winning candidate = 0.65 X 80n = '52n' Number of valid votes received by losing candidate = 0.35 X 80n = '28n' So, 52n - 28n = 1,920 Or, 24n = 1,920 Or, 'n' = 80 Number of valid votes = 80 X 80 = 6,400

What will come in place of the question mark (?) in the following series?
50, 25, 25, ?, 75, 187.5
12.06 × 19.02 + 12.94 × 14.87 + 152.09 = ?% of 498.98Â
?% of (136.31 ÷ 16.97 × 75.011) = 179.98
15.98% of 399.76 × 2.98 = ?% of 599.93Â
