Which of the following statements would be sufficient to determine the numerical code for “rose”?
I. The code for ‘roses are red’ is ‘719’.
II. The code for ‘I love red roses as gift’ is written as ‘574186’.
Answer:
a. 1 alone is sufficient while 2 alone is not sufficient.
b. 2 alone is sufficient while 1 alone is not sufficient.
c. Neither 1 nor 2 is sufficient.
d. Both 1 and 2 are sufficient.
Ans: C

Even when combining both statements, we still cannot definitively assign a number to “rose.” There’s no direct mapping provided to deduce which specific digit corresponds to “rose” in either phrase.
Identify the next number sequence:
134, 154, 138, 158, 142, 162, 146
a. 160
b. 162
c. 165
d. 166
Ans: D
The pattern alternates addition:
134 + 4 = 138, 138 + 4 = 142, 142 + 4 = 146
154 + 4 = 158, 158 + 4 = 162, 162 + 4 = 166
A shopkeeper sells chocolates priced at Rs.300 each. Which statements are sufficient to determine the net profit?
Statement I: The number of chocolates sold.
Statement II: The cost price of each chocolate
a. Each statement by itself is sufficient.
b. Both statements combined are sufficient for an answer, but neither statement individually is sufficient.
c. Statement I is sufficient on its own, whereas Statement II is not sufficient alone.
d. Statement II is sufficient on its own, while Statement I is not sufficient alone.
Ans: B
Statement I provides the quantity sold, while Statement II provides the cost price. Together, they are enough to calculate net profit, but each alone is insufficient.
All girls are fairies.
No fairy will cry.
Answer options:
a. Some crying things are fairies.
b. No girl will cry.
c. All fairies cry.
d. None of the given options.

Arguments: Numerous regions in the country are facing a critical water shortage and a decline in water table levels. What measures should be implemented to tackle this water crisis?
Actions:
I. The water supply authority should promptly arrange to deliver water to the affected areas.
II. Residents in these regions should work to minimize water wastage.
a. Only Action I is sufficient.
b. Only Action II is sufficient.
c. Both Actions I and II are sufficient.

Ans: C
Action I addresses the urgent need to supply water to impacted areas, which is essential in the short term to mitigate the crisis. Action II focuses on reducing water wastage, crucial for long-term sustainability and preventing future shortages.
You have a two digit number represented as XY, where X is the first digit and Y is the second digit. Determine which statement is sufficient to find its value.
Statement I: The number is a multiple of 52.
Statement II: The sum of the digits x and y equals 7.
a. Each statement alone is sufficient.
b. Both statements together are sufficient but neither statement alone is sufficient.
c. Statement I alone is sufficient, but Statement II alone is not sufficient.
d. Statement II alone is sufficient, but Statement I alone is not sufficient.
Ans: C
Statement I alone is sufficient because there is only one two-digit multiple of 52, which is 52. Statement II is not sufficient alone since multiple numbers can have digits that sum to 7.
A group of student is lined up outside the school cafeteria for lunch. Given the following statements, what is the position of student A from the left?

Statement II: Student A is 12th from right and student B is 30th from the left.
a. Each statement alone is sufficient.
b. Both statements together are sufficient but neither statement alone is sufficient.
c. Statement I alone is sufficient, but Statement II alone is not sufficient.
d. Statement II alone is sufficient, but Statement I alone is not sufficient.

Infosys Full Process & PYQs 2025 Pseudo Code:

What is value for b=18?
Function Calculate(Integer b)
If(b EQUALS 1)
Return 0
Else
Return 5 + Calculate(b / 2)
End Function Calculate
Ans: 20
So, when b is 18, the function will calculate as follows:
Calculate(18) returns 5 + Calculate(9).
Calculate(9) returns 5 + Calculate(4).
Calculate(4) returns 5 + Calculate(2).
Calculate(2) returns 5 + Calculate(1).
Calculate(1) returns 0.
Therefore, the final result is:
5 + 5 + 5 + 5 + 0 = 20
Integer a,b,c
Set b=300, a=5, c=1
if(b>a)
b=a
Else
a=b
End if
For(each b from 0 to 5)
End for
a=a+1
Print a+c
Ans: 12
Variable Initialization:
b = 300
a = 5
c = 1
If Condition:
Check if b > a:
Since 300 > 5 is true, we execute the then block.
b = a → b = 5.
For Loop:
For (each b from 0 to 5):
This loop iterates through values 0, 1, 2, 3, 4, 5.
However, the loop body is empty, so no operations are performed during this iteration.
Increment a:
After the loop, a = a + 1:
a = 5 + 1 → a = 6………..11
Print Statement:
Finally, we print a + c:
Print 11 + 1 → Print 12.
What will be the output of following program?
Set float = 0.1
If(f==0.1)
display “Yes”
Else
display “No”
End if
Ans: Yes
Due to the undefined variable f, the pseudo code would result in an error when executed. If the intention was to check float, the condition should be If (float == 0.1) instead, which would correctly display “Yes”.
What will be the output of following program
Set Integer array=[2,4,0,1,6,0]
Set integer res= array[2]/array[4]
Display res;
Ans: 0
An array named array is initialized with the values [2, 4, 0, 1, 6, 0].
The indices of the array are as follows:
array[0] = 2
array[1] = 4
array[2] = 0
array[3] = 1
array[4] = 6
array[5] = 0
Calculation of res:
Set Integer res = array[2] / array[4]
array[2] is 0 and array[4] is 6.
Therefore, the calculation is:
res=0/6=0

Integer i,j
for(each i from 0 to 2)
for(each j from 0 to i)
print “play”
end for
end for
Ans: play will get printed 6 times
Outer Loop Iterations:
i=0: Inner loop runs 1 time (prints “play”)
i=1: Inner loop runs 2 times (prints “play” twice)
i=2: Inner loop runs 3 times (prints “play” three times)
Total Prints:
1 + 2 + 3 = 6
Output:
“play” printed 6 times
Integer p,q,r
Set p=1, q=3, r=1
p = p^q
q=r^q
r = p^q
