Quantitative Aptitude - Geometry - Triangles - Let P be an interior point Quantitative Aptitude - Geometry - Triangles Question Let P be an interior point of a right-angled isosceles triangle ABC with hypotenuse AB. If the perpendicular distance of P from each of AB, BC, and CA is 4 (√2 - l) cm, then the area, in sq cm, of the triangle ABC is Answer 16 Solution From CAT 2017 - Quantitative Aptitude - Geometry - Triangles, we can see that, PQ = PR = PS = 4(√2-1) CS = PR (PC)^2 = (PS)^2 + (CS)^2 On solving, we get, PC = 4√2(�

Quantitative Aptitude - Geometry - Triangles - Let ABC be a right-angled triangle Quantitative Aptitude - Geometry - Triangles Question Let ABC be a right-angled triangle with BC as the hypotenuse. Lengths of AB and AC are 15 km and 20 km, respectively. The minimum possible time, in minutes, required to reach the hypotenuse from A at a speed of 30 km per hour is Answer 24 Solution As per the question from CAT 2017 - Quantitative Aptitude - Geometry - Triangles, BC^2 = AB^2 + AC^2 = 625 BC = 25 Shortest Distance from A to hypotenus
