JEE Main 2024 Mathematics question
A variable line L passes through the point (3, 5) and intersects the positive coordinate axes at the points A and B. The minimum area of the triangle OAB, where O is the origin, is :
Answer: (A)
Solution
Let the line be x/a + y/b = 1 with 3/a + 5/b = 1, so b = 5a/(a − 3) (a > 3). Area = ½ab =
