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?

- $P, Q$
- $P, Q, T$
- $R, S, T$
- $Q, R, S$

This Contour Line problem with a graphical picture asked in each set this year ( both set 1 and set 2 papers) . In both sets questions are logical only .

No prior experience is required to solve them other than logical mind .

Now coming to this set 1 question,

given water level value is 525 m .

600 > P >550, 550 > Q > 525 , 500 >R > 450, 450 > S > 425 , 525 >T> 500

now to get submerged the value should be Less than 525

that condition is satisfied by R, S, and T only . Because P and Q have above 525 value.

so the answer is R, S, T -- which is option C .
