Answer: A) Assembler Explanation: Assemblers are used to translate a program written in a low-level assembly language into a machine code (object code) file so it can be used and executed by the computer.   Hence, Assembler is the translator program used in assembly language.

Answer: B) 40 Explanation: The third proportional of two numbers p and q is defined to be that number r such that p : q = q : r.   Here, required third proportional of 10 & 20, and let it be 'a' => 10 : 20 = 20 : a 10a = 20 x 20 => a = 40   Hence, third proportional of 10 & 20 is 40.

Answer: C) Fluorine Explanation: Electronegativity refers to the ability of an atom to attract shared electrons in a covalent bond. The higher the value of the electronegativity, the more strongly that element attracts the shared electrons. Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element and lithium is the least.

Answer: C) Zn Explanation: In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic bonds. Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the other elemental substances.   Examples of metals are aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc.   Here Se - Selenium is an element but is not a metal, S - Sulphur is not a metal and I - Iodine is also not a metal.   Hence, Zn - Zinc is the only metal in the given options.

Answer: B) 3.28084 Explanation: We know that,  1 meter = 100 cms.  => 1 meter = 3.28084 feet.

Answer: A) A Explanation: The quadratic equation whose roots are reciprocal of 2x2+5x+3=0 can be obtained by replacing x by 1/x.   Hence, 2(1/x)(1/x)+ 5(1/x) + 3 = 0   => 3x2+5x+2=0
