उत्तर : 1. "131 calls"
व्याख्या :
Answer: A) 131 calls Explanation: 1st supporter recieve 440 calls 2nd supporter recieve 360 calls 3rd supporter recieve 300 calls So total calls = 1100 calls ; Calls this month= 1500 So remaining calls to be distributed is 400 So Now Ratio 1st:2nd:3rd ==> 440:360:300=> 22:18:15 Now No. of More Calls 2nd supporter will get => [18/(22+18+15)] x 400=> (18/55) x 400 => 131 CallsSo 131 more Calls than last month.

उत्तर : 2. "2x^2"
व्याख्या :
Answer: B) 2x^2 Explanation: In an algebraic expression, like terms are terms that contain the same variables raised to the same powers. Calculating x-squared plus x-squared is a matter of combining like terms. Now x^2 + x^2 = 2x^2 Hence, x-squared plus x-squared is equal to 2 times x squared.

उत्तर : 3. "Cytoplasm"
व्याख्या :
Answer: C) Cytoplasm Explanation: Right after that, the mRNA enters the cytoplasm through nuclear pores. There, it could be translated into proteins by ribosomes. This process is called translation. Translation occurs in the cytoplasm whereas transcription occurs in the nucleus.

उत्तर : 2. "K"
व्याख्या :
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.
