In a knockout football competition 23 teams
participated. What was the least number of matches they needed to play to decide the winner?Solution
Number of team-23 Every team except the winner will be defeated once Since there is no possibility for the teams to be defeated twice, the total number of matches required would be 23-1= 22 Hence, 22 are the correct.
Simplify: 6(x³ − 2x² + 3x) − (x³ + 2x − 3).
Find the value of 16 X [(8 - 5) of 12 ÷ 4].
20 * 8 + 40% of 100 + 60% of 150 = ?
(64 × 16) ÷ (4 × 16) 3 × 256 2 = 4 ?
25% of 1000 + 10% of 150 – 22 × ? = 45
390/? = √256 + 3.5
4.7 × 3.5 + 4.2 × 4.5 = 22.5 × 3.5 - ?
540240 ÷ 24 ÷ 25 =?
Simplify-
x + 3(y + x – 2) – (x + y).
