In this post we will discuss the questions of height and distance which is part of the syllabus of quantitative aptitude. All the questions given below are important as they are previously asked in competition exams like GRE, GMAT, Math Olympiad, CAT, MAT, CMAT, SNAP, NMAT, SSC, SSC-CGL, SSC-CHSL, Banking , IBPS, SBI PO, SBI Clerk, RRB, NDA, AFCAT etc.
The problems of height and distance require knowledge of basic trigonometry function. If you are unaware of the concept of trigonometry, i would strongly suggest to complete that chapter first and then move on with height and distance questions
Height & Distance Aptitude Questions
Q1. One flies a kite with a thread 150 meter long. If the thread of kite makes an angle of 60º with the horizontal line, then the height of the kite from the ground (assuming the thread to be in a straight line) is
Q2. The angle of elevation of the top of a tower from two points A and B lying on the horizontal through the foot of the tower are respectively 15º and 30º. If A and B are on the same side of the tower and AB= 48 meter, then the height if the tower is;
Q3. A man standing at a point P is watching the top of a tower, which makes an angle of elevation of 30º. The man walks some distance towards the tower and then his angle of elevation of the top of the tower is 60º. If the height of the tower is 30m, then the distance he moves is?
Q4. An Aeroplane when flying at a height of 3125m from the ground passes vertically below another plane at an instant when the angle of elevation of two planes from the same point on the ground is 30º and 60º respectively. The distance between the two planes at that instant is?
Q7. The angle of elevation of an aeroplane from a point on the ground is 60º. After 15 seconds flight, the elevation changes to 30º, if the aeroplane is flying at a height of 1500 m, find the speed of the plane
Q8. There are two temples, one on each bank of a river just opposite to each other. One temple is 54m high. From the top of this temple, the angles of depression of the top and the foot of the other temple are 30º and 60º respectively. The length of the temple is;
