Answer: B) 8 Explanation: The easiest way would measure it through half a liter water bottle. There are approximately 16.9 ounces(oz) of water in a 500ml water bottle.   Gallon is an imperial customary volume unit for the U.S.   As we have previously mentioned, the 16.9oz bottle is also known as 500ml in the metric system. According to U.S. standard, 1 gallon stands for 128 fluid oz.   Hence, Number of bottles in 1 gallon = 128/16.9 = 7.57 =~ 8.

Answer: A) 0.125 Explanation: 1/8 to convert into decimal, Find an equivalent fraction with a denominator of a power of 10. In this case, we will use 1000. 18 x 125125 = 1251000 This can now be written as a decimal with 3 decimal places (because we have thousandths. i.e, 0.125   Hence, 18 as a decimal = 0.125

Answer: D) All the above Explanation: The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components::  1. The brain  2. The spinal cord The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement. The brain can be divided into four main lobes: temporal, parietal, occipital and frontal.   The spinal cord serves as a conduit for signals between the brain and the rest of the body.

Answer: C) 9 Explanation: Given   6 = 3 => Number of letters in SIX = 3   12 = 6 => Number of letters in TWELVE = 6   14 = 8 => Number of letters in FOURTEEN = 8   Similarly,   22 = 9 => Number of letters in TWENTY TWO = 9           Therefore, 22 = 9.

Answer: A) Thiruvananthapuram Explanation: Vikram Sarabhai Space Centre is located at Thiruvananthapuram, Kerala.   This is the lead centre of ISRO responsible for the design and development of launch vehicle technology focusing on rocket and space vehicles for India's satellite programme.

Answer: C) 243 Explanation: Digits are 0,1,2,3,4,5,6,7,8,9. So no. of digits are 10   First all possible case => 9(0 excluded) x 10 x 10 = 900   Second no repetition allowed =>9 x 9 x 8 = 648   Third all digits are same => 9 (111,222,333,444,555,666,777,888,999)   Three digit numbers where two of the three digits are same = 900 - 648 - 9 = 243 ;

Answer: B) K Explanation: For neutral atoms, the periodic trends in atomic size can be described like this Atomic size decreases when going from left to right across a period,Atomic size increases when going from top to bottom down a group.   Let's use these trends to try and figure out which atom would have the largest radius. If you look at elements that are located in the same group, potassium will have a larger atomic radius when compared with sodium. Likewise, bromine will have a larger atomic radius when compared with chlorine. Now focus on potassium and bromine. Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.

Answer: A) 15 Explanation: Using BODMAS Rule, First solve division, mutiplication and Addition So here 10/2 = 5 Then 2 x 5 =  10 Now, 5 + 10 = 15.   Hence, 5 + 2 x 10/2 = 15.
