Correct Option - 4
Detailed Solution:

Any tangent to y2 = 24x at (a, b) is by = 12 (x + a) therefore   Slope = 1 2 β  

and perpendicular to 2x + 2y = 5 Þ 12 = b and a = 6 Hence hyperbola is x 2 6 2 y 2 1 2 2  = 1 and normal is drawn at (10, 16)

therefore equation of normal  3 6 x 1 0 + 1 4 4 y 1 6 = 3 6 + 1 4 4 x 5 0 + y 2 0 = 1  This does not pass through (15, 13) out of given option.
