Question
In an election, two candidates A and B participated.
of the voters promised to vote for A and rest promised to vote for B. On the voting day 25% of the voters went back on their promise to vote for A and 30% of the voters went back on their promise to vote for B. Find the total number of voters, if B wins by 180 votes.Solution
Let the voters for A be 200 Unit And voters for B be 300 Unit Difference of (260 - 240) units = 180 votes 20 units = 180 votes 1 unit = 9 votes 100 units = 900 votes Voters for A = 200 units Voters for B = 300 units Total voters = 500 units Total voters = 9 x 500 = 4500 votes
- If 2a + b = 15 and ab = 18, then the value of (4a² - b²) .
If ( p = 40 - q - r ) and ( pq + r(q + p) = 720 ), then find the value of ( p2 + q2 + r2).
- If x² - 2x + 1 = 0, then find the value of (x² + x⁻²)(x² + x⁻²).
If (a + b) = 7 and ab = 9, then find the value of (a2 + b2).
- If x 4 + 1/x 4 = 194, x > 0, then find the value of x + 1/x + 2.
