Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Answer: Plunge= 15.94° Given, elevation of point C = 400m, elevation of point D = 300m, Horizontal distance between point C and D = CD = 3.5 cm (on map) = 3.5 × 100 m tan(Plunge) = (Elevation of point C - Elevation of point D) / (3.5 × 100 m) = (400m - 300m) / 350m = 2 / 7 Plunge = arctan (2/7) = 15.94°
