उत्तर : 1. "0.5"
व्याख्या :

Answer: A) 0.5 Explanation: In mathematics, a geometric progression, also known as a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.   Herein the given sequence, 4, 2, 1, 0.5, 0.25, 0.125,... Common Ratio r = 2/4 = 1/2 = 0.5/1 = 0.25/0.5 = 0.125/0.25 == 0.5.

उत्तर : 2. "Intracellular transport"
व्याख्या :

Answer: B) Intracellular transport Explanation: A cytoskeleton is the frame that gives shape to a cell. And also it offers support, and facilitates movement through three main components: microfilaments, intermediate filaments, and microtubules.   The cytoskeleton helps the cell move in its environment and controls the movement of all of the cell's interior workings.

उत्तर : 3. "(p + 4) times"
व्याख्या :

Answer: C) (p + 4) times Explanation: Let the two no's be a and b;Given product of the no's is p = ab;If the each nos is increased by 2 then the new product will be (a+2)(b+2) = ab + 2a + 2b + 4= ab + 2(a+b) + 4= p + 2(a+b) + 4Hence the new product is (p+4) times greater than twice the sum of the two original numbers.

उत्तर : 1. "2880"
व्याख्या :

Answer: A) 2880 Explanation: There are total 9 places out of which 4 are even and rest 5 places are odd.   4 women can be arranged at 4 even places in 4! ways.   and 5 men can be placed in remaining 5 places in 5! ways.   Hence, the required number of permutations  = 4! x 5! = 24 x 120 = 2880

उत्तर : 1. "Hertz"
व्याख्या :

Answer: A) Hertz Explanation: CPU speed is the central factor in a computer's performance. And this CPU speed depends on the processor in the CPU chip. In a computer, clock speed refers to the number of pulses per second generated by an oscillator that sets the tempo for the processor. Clock speed is usually measured in Hertz (Hz).   But now-a-days, a pure processor's performance is measured in MIPS (Millions of Instructions Per Second). As here in the question, how a processor's speed is measured is asked and it is Hertz.    Hence, Processor's speed of a computer is measured in Hertz(Hz) [MHz, GHz].
