DCE - Delhi College of Engineering conducts entrance test which contains physics, chemistry and Maths. Here, I will be providing information on DCE Maths Paper.

If in a projectile motion range R is maximum then relation between H and R is

(a) H = R/2 (b) H = R/4 (c) H = 2R (d) H = R/8

A line passes through the point of intersection of the lines 3x + y + 1 = 0 and 2x – y + 3 = 0 and makes equal intercepts with axes. Then equation of the line is

(a) 5x + 5y – 3 = 0 (b) x + 5y – 3 = 0 (c) 5x – y – 3 = 0 (d) 5x + 5y + 3 = 0

The common tangent of the parabolas y2 = 4x and x2 = –8y is

(a) y = x + 2 (b) y = x – 2 (c) y = 2x + 3 (d) none of these
