(A) 6F
(B) 6G
(C) 6H
(D) 6I
Ans: (A) 6F.
Sol:- The series seems to be a combination of numbers and letters in an alternating pattern. Each number is followed by a letter corresponding to its position in the English alphabet.
1A, 2B, 3C, 4D, 5E…
Following this pattern, the next term would be 6F. - Which term will come next in the series: AXB, BYC, CZD, DYE,?
(A) EXF
(B) EYF
(C) EZA
(D) EAF
Ans: (A) EXF
Sol:- The pattern in the given series is as follows:
The first letter moves one step forward in the alphabet (A → B → C → D → E).
The second letter moves one step backward in the alphabet (X → Y → Z → Y → X).
The third letter moves one step forward in the alphabet (B → C → D → E → F).
Applying this pattern, the next term in the series would be EXF. - If BD, DG, GK, then the next term is:
(A) KM
(B) KJ
(C) KP
(D) JN
Ans: (C) KP
Sol:- pattern appears to involve moving three letters forward in the alphabet:
B -> D (+2)
D -> G (+3)
G -> K (+4)
Following this pattern, the next letter after K would be P. H
So, following this pattern, the next number would be 5. Converting 5 back to a letter, we get:
K -> P
So, the next term is KP - If 3F, 6K, 9P, then the next term is:
(A) 12U
(B) 12W
(C) 12S
(D) 12T

Continuing this pattern, the missing letter after G would be three positions ahead, resulting in J.
So, the correct answer is J - If the position of the 1st and the 14th alphabets, the 2nd and the 15th alphabets, and so on up to the 13th and the 26th alphabets, are interchanged, then which alphabet will be 7th to the right of the 10th alphabet from the right end?
(a) A
(b) C
(C) D
(d) B
ANS:- (b) C
Sol:- To solve this problem, let’s first identify the new positions of the alphabet after the interchange:
After the interchange:
The 1st alphabet (A) moves to the 14th position.
The 2nd alphabet (B) moves to the 15th position.
And so on, until:
The 13th alphabet (M) moves to the 26th position.
Now, we are asked to find the alphabet that will be 7th to the right of the 10th alphabet from the right end. This means we need to count 10 alphabets from the right end and then move 7 positions to the right from there.
From the right end:
The 10th alphabet is N (since M moves to the 26th position).
7 positions to the right of N is C.
So, the alphabet that is 7th to the right of the 10th alphabet from the right end is C.
Therefore, the correct option is (b) C - Rohit is standing facing North. He goes 30 meters ahead and turns left and goes for 15 meters. Now he turns right, goes for 50 meters, and finally turns to his right and walks. In which direction is he facing
A) North
B) East
C) South
D) West
ANS:- B) East.
Sol:- Let’s analyze Roshan’s movements:
Roshan starts facing North.
He moves 30 meters ahead (still facing North).
He turns left, which means he is now facing West.
He moves 15 meters.
He turns right, which means he is now facing North again.
He moves 50 meters.
Finally, he turns right again, which means he is now facing East.
So, after all the movements, Roshan is facing East.
Therefore, the correct answer is option B) East. - Which direction is exactly opposite to the north?
(A) East
(B) South
(C) West
(D) Northeast
ANS:- (B) South.
Sol:- The direction exactly opposite to the north is south.
Therefore, the correct answer is option (B) South. - If A walks 5 km towards the east, then turns right and walks 10 km, what is the straight-line distance between A’s starting point and ending point?
(A) 10 km
(B) 12 km
(C) 13 km
(D) 15 km
ANS:- 11.18 km.
Sol:- Let’s visualize A’s movements:
A walks 5 km towards the east.
Turns right (A is now facing south) and walks 10 km.
This forms a right-angled triangle, where one side is 5 km (the initial eastward walk), another side is 10 km (the southward walk), and we need to find the hypotenuse, which is the straight-line distance between A’s starting point and ending point.
Using the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b):
c² = a² + b²
Substituting the given values:
c² = 5² + 10²
c² = 25 + 100
c² = 125
Taking the square root of both sides to solve for c:
c = √125 ≈ 11.18 km
So, the straight-line distance between A’s starting point and ending point is approximately 11.18 km.
Therefore, the answer is option (C) 11.18 km. - A person walks 20 meters towards the north and then turns left and walks 30 meters. How far is the person from the starting point?
(A) 20.04 meters
(B) 36.06 meters
(C) 40.5 meters
(D) 50 meters
ANS:- (B) 36.06 meters
Sol:- To find the distance from the starting point, we can use the Pythagorean theorem since the person has walked in a right-angled triangle.
Let’s denote:
The distance walked towards the north as side A (20 meters).
The distance walked after turning left as side B (30 meters).
Then, using the Pythagorean theorem:
Hypotenuse² = Side A² + Side B²
Hypotenuse² =20² + 30²
= 400 + 900
= 1300
Taking the square root of both sides:
Hypotenuse = √1300
Hypotenuse ≈ 36.06
So, the person is approximately 36.06 meters from the starting point. The correct answer is (B) 36.06 meters - What will be his new direction if the current direction is South-East and a person turns 45 degrees to his right?
(A) South
