A contour line joins locations having the same height above the mean sea level. The following is a contour plot of a geographical region. Contour lines are shown at 25 m intervals in this plot.
If in a flood, the water level rises to 525 m, which of the villages P, Q, R, S, T get submerged?
(A) P,Q
(B) P,Q,T
(C) R,S,T
(D) Q,R,S
Answer: (C)
Explanation: Given data – height of all villages
- P = 575
- Q = 525
- R = 475
- S = 425
- T = 500
Villages below the flood level – 525m are
- R <500m
- 425m<= S<=450m
- 500m <=T<= 525m
Therefore option C is correct.
