Q1Study the figure showing the route of a clerk distributing files for a drinking-water scheme. From the panchayat office, how far and in which direction is the final collection point?
From the figure, the clerk walks 12 km east and then 5 km south. Net displacement is 12 km east and 5 km south from the panchayat office. Shortest distance = √(12^2 + 5^2) = √(144 + 25) = 13 km. The final point lies east and south of the start, so the direction is South-East. The displacement is a 5-12-13 triangle towards South-East. The 17 km option comes from adding the route lengths.
Q2Study the figure. During a school scholarship camp, a clerk walks from the registration desk to the final grant counter along the shown path. What is the shortest distance and direction of the final grant counter from the registration desk?
The route shows 9 km east, 12 km south, and 4 km west. Net eastward movement = 9 - 4 = 5 km, and net southward movement = 12 km. The shortest distance is sqrt(5^2 + 12^2) = sqrt(25 + 144) = 13 km. The final grant counter is east and south of the registration desk, so the direction is South-East. After cancelling the opposite east-west legs, the net displacement is 5 km east and 12 km south. The 25 km option adds the route lengths instead of taking the shortest distance.
Q3In a Kota school chess team, Dev and Rajni are children of the same parents. Bhanwar is Dev's father. Kavita is Rajni's mother. Sunita is Bhanwar's sister. How is Sunita related to Kavita?
Dev and Rajni have the same parents. Bhanwar is Dev's father, so he is also Rajni's father. Kavita is Rajni's mother, so Bhanwar and Kavita are the parents. Sunita is Bhanwar's sister; therefore, Sunita is Kavita's husband's sister. Sunita is not Kavita's own sister; she is the sister of Kavita's husband, Bhanwar. The trap is to ignore the shared-parent condition for Dev and Rajni.
Q4Which Venn diagram best represents the relationship among: Rajasthan, India, Asia?
Rajasthan is a state within India, and India is a country within Asia. This is a nested (concentric) relationship: Rajasthan ⊂ India ⊂ Asia.
Q5At a chess score table, Deepak says to Nisha, "Your mother's only daughter is my son's mother." How is Deepak related to Nisha?
Nisha's mother's only daughter is Nisha herself. Deepak says that this person is his son's mother. Therefore, Nisha is the mother of Deepak's son. Hence, Deepak is Nisha's husband. Replace "your mother's only daughter" with Nisha. The trap is to treat that daughter as Nisha's sister, although the word "only" rules that out.
