91. One day Rahul left home and walked 5 km northwards, turned right and walked for 10km and turned left and walked 5 km more and finally turned left and walked 10km. How many kilometers will he have to walk to reach his home straight?
(A) 15 km
(B) 10 km
(C) 25 km
(D) 30 km
Answer:
(B) 10 km
Explanation:
He walks 5 km North. Turns right (East) for 10 km. Turns left (North) for 5 km. Turns left (West) for 10 km. His westward movement perfectly cancels his eastward movement. He is purely 10 km (5+5) straight North of his home.
92. Read the following statements: Team A has scored more goals than Team B Team C has scored fewer goals than Team B Team A has scored fewer goals than Team C. If the first two statements are true, the third statement is
(A) True
(B) False
(C) Can be both True or False
(D) Cannot be determined
Answer:
(B) False
Explanation:
Statement 1 means A > B. Statement 2 means B > C. Combining these yields A > B > C. Statement 3 claims A < C, which directly contradicts the logical conclusion A > C. Therefore, the third statement is definitively False.
93. Pointing to a photograph, a man said, “I have no brother, and that man’s father is my father’s son.” Whose photograph was it?
(A) His son
(B) His own
(C) His father
(D) His nephew
Answer:
(A) His son
Explanation:
Since the speaker has no brother, “my father’s son” can only be the speaker himself. Therefore, substituting this into the sentence gives: “that man’s father is ME.” If the speaker is the father of the man in the photo, the photograph is of his son.
94. If in a certain language, NOIDA is coded as OPJEB, how is DELHI coded in that language?
(A) CDKGH
(B) EFMIJ
(C) FGNJK
(D) IHLED
Answer:
(B) EFMIJ
Explanation:
Each letter in the original word is shifted forward by one alphabetical position (N+1=O, O+1=P, I+1=J, D+1=E, A+1=B). Applying this exact same +1 shift to DELHI yields D+1=E, E+1=F, L+1=M, H+1=I, I+1=J → EFMIJ.
95. Riya goes 30 km towards North from a fixed point, then after turning to her right she goes 15 km. After this she goes 30 km after turning to her right. How far and in what direction is she from her starting point?
(A) 10 m east
(B) 30 m east
(C) 15 m east
(D) 20 m west
Answer:
(C) 15 m east
Explanation:
She goes 30 km North. Turning right puts her facing East, where she goes 15 km. Turning right again puts her facing South, where she goes 30 km. The southward journey perfectly cancels the northward journey, leaving her 15 km exactly to the East of her starting point. (Note: The exam option typo uses ‘m’ instead of ‘km’).
