Pavan and Sravan are two persons. If Pavan works with his actual efficiency and Sravan twice of his actual efficiency then it takes 25 days to complete the work. But If Pavan works twice of his actual efficiency and Sravan with his normal efficiency then the work is completed in 20 days. How many days would it take if Sravan alone works with his actual efficiency (in Days)?
Which of the following statement(s) are true with respect to the concept of ‘EFFICIENCY’ as used in mainstream economics? 1. Efficiency occurs when no possible organization of production can make anyone better off without making someone else worse off. 2. An economy is clearly inefficient if it is inside the Production Possibility Frontier (PPF). 3. At a minimum, an efficient economy is on its Production Possibility Frontier (PPF). 4. The terms such as ‘Pareto Efficiency’, ‘Pareto Optimality’ and ‘Allocative Efficiency’ are all essentially one and the same which denote ‘efficiency in resource allocation’. Select the correct answer using the code given below:

(C) An algorithm is expressed in a graphical form known as a flowchart (D) An algorithm can have an infinite sequence of instructions. Choose the correct answer from the options given below:
In the following question, there are six sentences marked S1, S6, P, Q, R and S. The positions of S1 and S6 are fixed. Choose one of the options given below which would be the most logical sequence of the sentences in the passage. S1- While the judiciary has many important roles to fulfill, the ones that stand out in the current political climate are: P- Two, to protect the fundamental and other rights of the citizens of India. Q- It is the judiciary’s duty to ensure that whatever measures are enacted by the legislature or the executive are in keeping with the Constitution.  R- This means that if it has reason to believe that legislative measures go against the Constitution of the country, it can strike them down.  S- One, to act as guardian and interpreter of the Constitution. S6- Similarly, if these measures violate the fundamental rights of the citizens or even other rights, the judiciary can stall or end them.
A tangent is drawn from a point p outside the circle, which touches the circle at point A and B, another tangent is drawn from a point E on the circumference on the circle, which touches the line PA and PB at C and D, if PC measures 8 cm, PD measures 9 cm and CD measures 7 cm, then find the radius of circle.
Consider the following two C code segment. Y and X are one- and two-dimensional arrays of size n and n × n respectively, where 2 ≤ n ≤ 10. Assume that in both code segments, elements of y are initialized to 0 and each element X[i] [j] of array X is initialized to i + j. Further assume that when stored in main memory all elements of x are in same main memory page frame. Code segment 1:                 //initialize elements of y to 0                 //initialize elements X[i] [j] of X to i+j                       for (i = 0; i < n; i++)                                 Y[i] += X[0] [i]; Code Segment 2:                 //initialize elements of Y to 0                 //initialize elements X[i] [j] of X to i+j                        for (i = 0; i < n; i++)                                 Y[i] += X[i] [0]; Which of the following statements is/are correct? S1: Final contents of array Y will be same in both code segments S2: Elements of array X accessed inside the for loop shown in code segment 1 are contiguous in main memory S3: Elements of array X accessed inside the for loop shown in code segment 2 are contiguous in main memory
Efficiency of A is ¾ of the efficiency of B and efficiency of B is 80% of the efficiency of C. If A takes 120 days more than that of (B + C) working together to finish a work. In how many days; (A + B + C) can finish the whole work?
A and B can complete a work in 10 days and 15 days respectively. The efficiency of C is equal to the sum of efficiency of A and B. The efficiency of D is equal to the efficiency of A, B and C together. If A, B, C and D work together, they will complete the whole work in
