- Q1
In the problem-solving process, the step during which a solution is divided into sub solutions and arranged in proper order to solve the problem is
analyzing the problem
planning the solution of the problem
defining the problem
selecting the solution of the problem
45s - Q2
Consider the given algorithm
Step 1: Start
Step 2: INPUT A
Step 3: IF A> 0 THEN GOTO Step 4 ELSE GOTO Step 7
Step 4: A = A -1
Step 5: PRINT A
Step 6: GOTO Step 3
Step 7: Stop
If the input is 5, then the output of this algorithm is
4 3 2 1 0
4 3 2 1
5 4 3 2 1
5 4 3 2 1 0
45s - Q3
Consider the given algorithm
Step 1: Start
Step 2: A = 5, B = 10, C =15
Step 3: X = A + B + C
Step 4: Y = X / 3
Step 5: Output Y
Step 6: Stop
The output of the given algorithm will show the
division of three numbers
sum of three numbers
average of three numbers
largest number from three numbers
45s - Q4
In the problem-solving process, the step during which the number of possible solutions is determined is
selecting the solution of the problem
defining the problem
analysing the problem
planning the solution of the problem
