In an election between two candidates 75% of the voters cast their votes, out of which 4% of the votes were declared invalid. A candidate got 9,261 votes which were 75% of the total valid votes. Find the total number of voters enrolled in that election.
1. A17,150
2. B17,000
3. C16,800
4. D16,500
Answer (A)
9,261 = 75% of valid votes, so valid = 9261/0.75 = 12,348. Valid = 96% of cast votes (4% invalid), so cast = 12348/0.96 = 12,862.5. Cast = 75% of enrolled, so enrolled = 12862.5/0.75 = 17,150 (option A).

1. A56 cm
2. B70 cm
3. C84 cm
4. D100 cm
Answer (B)
11 km = 1,100,000 cm; one revolution covers one circumference, so circumference = 1,100,000 ÷ 5000 = 220 cm. Circumference = πd ⇒ 220 = (22/7)d ⇒ d = 220×7/22 = 70 cm.
