Study the survey of India toposheet G43S10 given and answer the following questions.

(i) Which is the largest settlement? Name and identify it.

(ii) Identify a steep slope shown on the map and give four figure grid reference of the same.

The ordnance survey maps of 1:50,000 scale have contours drawn at the vertical interval of 20 m. Although the contour interval is 20 m, in the topographical maps one finds the heights shown as 100 m. To make the contour maps distinct, every fifth line in multiple of 20 m is accentuated and this is called Index contour.
