Question
Find the total number of voters in the city.
Statement I: A and B contested in an election. 40% votes were invalid. A got 65% of the valid votes and B got 25% of the invalid votes. Statement II: Total votes (valid + invalid) obtained by A is 1035.Solution
ATQ, From Statement I, Let the total number of voters be 100x Invalid votes = 100x × 40/100 = 40x Valid votes = 100x − 40x = 60x Valid votes got by A = 60x × 65/100 = 39x Valid votes got by B = 60x − 39x = 21x Invalid votes got by B = 40x × 25/100 = 10x Invalid votes got by A = 40x − 10x = 30x So, Statement I alone is not sufficient. From Statement II, Total votes got by A is 1035 So, Statement II alone is not sufficient. From Statement I and II, 39x + 30x = 1035 69x = 1035 x = 15 Total number of voters = 100 × 15 = 1500 Both statements are necessary to answer the question.
What will come in the place of question mark (?) in the given expression?
? = (266 × 276) ÷ (114 × 161) × 17
15% of ? = 30% of 320 + 17 ×√676 – 63.5 × 8
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
(350/?) = 23 + 33
416 ÷ 8 + 132 – 25% of 420 = ?
{(481 + 426) 2 - 4 × 481 × 426} = ?
- What will come in place of (?) in the given expression.
(2/3 of 96) ÷ (4/5 of 25) = ? 311 × 17 = ? + 2482
5490 ÷ 15 × 18 + 450 = ?
144 (1/2) × 14 – 28 = 7 × ?
