Question

In the given diagram, ovals are marked at different heights (h) of a hill. Which one of the following options P, Q, R, and S depicts the top view of the hill? 

• A. P
• B. Q
• C. R
• D. S

Hint:

A top view of a hill with increasing altitude towards the center should show concentric circles. This corresponds to the shape in option (R).

Answer 1

The Correct Option is C

- The given diagram shows a hill with horizontal cross-sections at various altitudes. The oval-shaped contours represent the cross-sections at different heights. The shape and size of these contours change as the altitude changes. The given diagram suggests that the hill has a peak in the center, and the altitude decreases as we move outward from the center.
- Option (P): This option shows an irregular shape, and the contours are not concentric. This irregularity doesn't correspond to the shape of a typical hill, which is often depicted with concentric contours. Hence, (A) is incorrect.
- Option (Q): This option shows a perfect symmetry of contours, but this doesn't match the irregularity of the hill shown in the diagram. The hill is expected to have a more gradual slope and irregular contours. Thus, (B) is incorrect.
- Option (R): This option shows concentric circles, which is characteristic of a hill with a peak at the center and decreasing altitude as we move outward. This matches the diagram perfectly, where the altitude decreases as we move away from the hill's peak. This makes (C) the correct answer.
- Option (S): This option shows a disorganized pattern of concentric circles, which doesn't correspond to the expected shape of a hill. The contours are not consistently decreasing in size as the altitude decreases. Hence, (D) is incorrect.
