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 : 3. "20"
Explanation :

Answer: C) 20 Explanation: We know that, Total probability = 1 Given probability of black stones = 1/4 => Probability of blue and white stones = 1 - 1/4 = 3/4 But, given blue + white stones =  9 + 6 = 15 Hence, 3/4 ----- 15  1   -----  ? => 15 x 4/3 = 20.   Hence, total number of stones in the box = 20.

Answer : 4. "All the above"
Explanation :

Answer: D) All the above Explanation: Most of the emissions of greenhouse gases (GHG) come primarily from burning fossil fuels (coal, hydrocarbon gas liquids, natural gas, and petroleum) for energy use and the major greenhouse gas is of course carbon dioxide (CO2) which comes from burning fossil fuels and land-use change. But methane (CH4) and nitrous oxide (N2O), which mostly come from agriculture and waste, are also significant GHGs and shouldn't be discounted.
