21. In the following problems, you are told something about the result, and you must determine what the contents of the boxes must have been, in order to obtain that result.
In these problems, the expression (number in box X) is abbreviated as (X).
For example: "Is (4) greater than (7)?"
means "Is (number in box 4) greater than (number in box 7)?"
In each of the following problems, no two boxes contain the same number.
Which of the boxes 1, 2, 3 CANNOT POSSIBLY contain the largest number, the smallest number?
Answer: Option A
Explanation:Given Box 4 = EITHER C or F
Also, (1) means number in Box 1.
For C,
IS (3) > (1) ? NO --(1)
IS (2) > (1) ? YES --(2)
For F,
IS (3) > (1) ? YES --(3)
IS (2) > (1) ? YES --(4)
IS (3) > (2) ? YES --(5)
ANSWER
Number in BOX 1 cannot be largest(refer (1), (2), (3) and (4)),

22. In the following problems, you are told something about the result, and you must determine what the contents of the boxes must have been, in order to obtain that result.
In these problems, the expression (number in box X) is abbreviated as (X).
For example: "Is (4) greater than (7)?"
means "Is (number in box 4) greater than (number in box 7)?"
In each of the following problems, no two boxes contain the same number.
Which of the boxes 1, 2, 3 CANNOT POSSIBLY contain the largest number, the smallest number?
Answer: Option D
Explanation:Given Box 4 = EITHER B or E
Also, (1) means number in Box 1.
For B,
IS (3) > (1) ? NO --(1)
IS (2) > (1) ? NO --(2)
IS (3) > (2) ? YES --(3)
Here, (2) has the smallest and (1) has the largest number of the three.
For E,
IS (3) > (1) ? YES --(4)
IS (2) > (1) ? YES --(5)
IS (3) > (2) ? NO --(6)
Here, (2) has the largest and (1) has the smallest number of the three.
Therefore Option (D)None of these.

23. The object of the following flow-chart is to rearrange the numbers in boxes 1, 2 and 3 in such a fashion that, at the end:
Box 3 will always contain the largest number,
Box 1 will always contain the smallest number,
However, this flow-chart is INCORRECT. As it stands, it will not accomplish the desired purpose.
Which one instruction must be changed to correct the flow-chart?
Answer: Option B
Explanation:The two conditions in the flowchart are :
Instruction 1 : IS (1) < (2) ? YES --(1)
Instruction 5 : IS (3) < (2) ? NO --(2)
ANSWER
The error is in Instruction 5, because BOX 3 will always contain the largest number and so the output to Instruction 5 will always be NO and the loop will end only on a YES.
