Answer : 2. "Mysuru"
Explanation :

Answer: B) Mysuru Explanation: India’s first smartcard-based Public Bicycle Sharing (PBS) initiative has launched in Mysuru, Karnataka on June 4, 2017. The cost of the project, partly funded by World Bank’s Global Environmental Facility, for the next six years is Rs 20.5 crore, covering the maintenance of the docking stations and bicycles.

Answer : 4. "3 : 2"
Explanation :

Answer: D) 3 : 2 Explanation: Let the speeds of the two trains be x m/sec and y m/sec respectively. Then, length of the first train = 27 x meters, and length of the second train = 17 y meters. (27 x + 17 y) / (x + y) = 23 => 27 x + 17 y = 23 x + 23 y => 4 x = 6 y => x/y = 3/2.

Answer : 2. "OH-"
Explanation :

Answer: B) OH- Explanation: A conjugate acid, is a species formed by the reception of a proton (H+) by a base—in other words, it is a base with a hydrogen ion added to it. On the other hand, a conjugate base is what is left over after an acid has donated a proton during a chemical reaction. Hence, a conjugate base is a species formed by the removal of a proton from an acid. Because some acids are capable of releasing multiple protons, the conjugate base of an acid may itself be acidic. Represented as the following chemical reaction: Acid + Base ⇌ Conjugate Base + Conjugate Acid   The water molecule is the conjugate acid of the hydroxide ion after the latter received the hydrogen proton donated by ammonium. On the other hand, ammonia is the conjugate base for the acid ammonium after ammonium has donated a hydrogen ion towards the production of the water molecule. We can also refer to OH- as a conjugate base of H2O, since the water molecule donates a proton towards the production of NH+4 in the reverse reaction, which is the predominating process in nature due to the strength of the base NH3 over the hydroxide ion.

Answer : 1. "X"
Explanation :

Answer: A) X Explanation: The logic in the given puzzle is  Addition of numeric values of corresponding letters in the first three figures gives respective corresponding letter in fourth figure.  i.e, A = 1 , W = 23 , B = 2 => 2 + 1 + 23 =26 = 'Z' Similarly, L = 12, K = 11 , A = 1 => 1 + 11 + 12 = 24 = 'X' Here the missing letter is 'X'.
