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 : 2. "222.5 degrees"
Explanation :
Answer: B) 222.5 degrees Explanation: Apply the formula for finding the angle:Angle=(30h-(11/2)m( where m stands for minutes and h stands for hours)Hence, 30x11 - 11/2x35 = 330 - 192.5 = 137.5 degreesThe reflex angle = 360 - 192.5 degree = 222.5 degrees.

Answer : 1. "0.5"
Explanation :
Answer: A) 0.5 Explanation: In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio. Herein the given sequence, 4, 2, 1, 0.5, 0.25, 0.125,... Common Ratio r = 2/4 = 1/2 = 0.5/1 = 0.25/0.5 = 0.125/0.25 == 0.5.
