Answer : 3. "O"
Explanation :

Answer: C) O Explanation: Given series is A F Z U G L T _ Starts with A A + 5 letters = F go to end of alphabet= Z Z - 5 letters = U from F go one more to G + 5 letters = L from U go one back to U, T - 5 letters = O   Second Method :: Change the letters to their corresponding number. A=1 B=2 C=3 ... Z=26 A F Z U G L T _ 1 6 26 21 7 12 20 ? Look at the pattern: the 1st and 3rd numbers = 27, 1+26 the 2nd and 4th numbers = 27, 6+21 the 5th and 7th numbers = 27, so the 6 and 8th would also equal 27. 27 - 12 = 15, so the letter is O.

Answer: C) 35 days Explanation: Distance d = 1200kmlet S be the speed he walks 15 hours a day(i.e 24 - 9)so totally he walks for 70 x 15 = 1050hrs. S = 1200/1050 => 120/105 = 24/21 => 8/7kmph given 1 1/2 of previous speedso 3/2 * 8/7= 24/14 = 12/7 New speed = 12/7kmph Now he rests 10 hrs a day that means he walks 14 hrs a day. time = 840 x 7 /12 => 490 hrs=> 490/14 = 35 days So he will take 35 days to cover 840 km.

Answer: C) Deuce Explanation: When both sides have won the same number of points then: when each side has won one, or two, points, the score is described as "15-all" and "30-all" (or "15-up" and "30-up"), respectively. However, if each player has won three points, the score is called as "deuce", not "40–all". From that point on in the game, whenever the score is tied, it is described as "deuce", regardless of how many points have been played.
