Answer :
Explanation :
In most cases, you will have no idea who you are competing with for a particular job. So this type of question really gives you a chance to open-up your strengths as a candidate with an emphasis on any assets that might separate you from the typical applicant. Think about what you bring to the table that you truly believe is unique - the easiest way to do is to think of your own personal stories that demonstrate your work ethic, skills, and dedication. Most people have some or all of those skills, but the unique stories are what make people stand out in interviews.

Answer : 1. "Binary Fission"
Explanation :
Answer: A) Binary Fission Explanation: Bacteria divided and reproduce by Binary fission. In this process, the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two replicates.

Answer : 1. "112"
Explanation :
Answer: A) 112 Explanation: 7 + 7 ÷ 7 + 7 x 7 + 7 - 7 ÷ 7 + 7 x 7= 7 + 1 + 49 + 7 - 1 + 49= 8 + 56 + 48= 56 + 56= 112

Answer : 4. "Covalent- network"
Explanation :
Answer: D) Covalent- network Explanation: Graphite is a covalent-network type of crystalline solid. There are two main categories of solids. 1. Crystalline solids and 2. Amorphous solids. Crystalline solids are those in which the atoms, ions, or molecules that make up the solid exist in a regular, well-defined arrangement. There are four types of crystalline solids : Ionic solids :— Made up of positive and negative ions and held together by electrostatic attractions. They’re characterized by very high melting points and brittleness and are poor conductors in the solid state. An example of an ionic solid is table salt, NaCl. Molecular solids :— Made up of atoms or molecules held together by London dispersion forces, dipole-dipole forces, or hydrogen bonds. Characterized by low melting points and flexibility and are poor conductors. An example of a molecular solid is sucrose. Covalent-network (also called atomic) solids :— Made up of atoms connected by covalent bonds; the intermolecular forces are covalent bonds as well. Characterized as being very hard with very high melting points and being poor conductors. Examples of this type of solid are diamond and graphite, and the fullerenes. As you can see below, graphite has only 2-D hexagonal structure and therefore is not hard like diamond. The sheets of graphite are held together by only weak London forces! Metallic solids :— Made up of metal atoms that are held together by metallic bonds. Characterized by high melting points, can range from soft and malleable to very hard, and are good conductors of electricity.
Q: A sum is equally invested in two different schemes on CI at the rate of 15% and 20% for two years. If interest gained from the sum invested at 20% is Rs. 528.75 more than the sum invested at 15%, find the total sum? 1718 05b5cc658e4d2b4197774bde2

Answer : 3. "Rs. 9000"
Explanation :
Answer: C) Rs. 9000 Explanation: Let Rs. K invested in each scheme Two years C.I on 20% = 20 + 20 + 20x20/100 = 44% Two years C.I on 15% = 15 + 15 + 15x15/100 = 32.25% Now, (P x 44/100) - (P x 32.25/100) = 528.75 => 11.75 P = 52875 => P = Rs. 4500 Hence, total invested money = P + P = 4500 + 4500 = Rs. 9000.

Answer : 3. "200"
Explanation :
Answer: C) 200 Explanation: 18 tens 20 ones, the given stateent can be split into 18 tens = 18 x 10 = 180 20 ones = 20 x 1 = 20 Then add both => 180 + 20 = 200 Hence, 18 tens 20 ones = 200.
Q: At an examination in which maximum marks are 500. K got 10% less than L, L got 25% more than M and M got 20% less than N. If K got 360 marks what percentage of marks was obtained by N ? 1716 05b5cc6c9e4d2b4197774dfab

Answer : 1. "80"
Explanation :
Answer: A) 80 Explanation: Let marks obtained by N = x M's marks = 0.80x L's marks = 1.25 (0.80x) K's marks = (0.90) (1.25) (0.80x) = 0.9x But 0.9x = 360 ⇒ x = 400 Percentage of Marks obtained by N = 400 x 100/500 = 80%
