## Aptitude Height and Distance Test Paper 416) The top and bottom of a flag on a building subtend angles of 60° and 30° respectively at a point B which is 48 meter away from the building. Find the height of the flag? - 32 m
- 32 √3 m
- 18.49 m
- 16 m
The Correctoption is(B)
Let height of building be AC = X and height of flag be CD = h. Put value of X in equation (1) from equation (2) 17) From the top of a lighthouse which is 90 m above the sea, the angle of depression of a ship is 60°. How far is the ship from the lighthouse? - 30 √3 m
- 30 m
- 17.34 m
- 20.5 m
The Correctoption is(A)
Let the height of the lighthouse above sea be AC and it is given 90 m. Ship is at point B so the distance between the base of lighthouse A and ship is AB. 18) The angles of elevation of the top of a tower from the top and bottom of a tree of height 15 m are 30° and 60° respectively. Find the height of the tower? - 7.5 m
- 22.5 m
- 11.5 m
- 20 m
The Correctoption is(B)
Let the CE be h meter. Height of tree be AD = 15m BE is the height of tower = BC + CE = 15 + h AB = CD, let it is = X m 3 h = 15 + h 2 h = 15 h = 7.5 m Height of tower = 15 + 7.5 = 22.5 m (Option B) 19) The distance between the tops of two trees is 16 m. If the heights of the trees are 20 m and 28 m respectively, find the horizontal distance between the two trees? - 192 m
- √192 m
- 256 m
- √256 m
The Correctoption is(B)
Let AE and BC be the heights of trees. AE = 28 m BC = 20 m Horizontal distance between trees AB = DC In Δ EDC, EC DC = 16 = 256 - 64 DC DC =√192 m (Option B) 20) There are two towers. The first tower of height 60 m casts a shadow of length 100m. At the same time if the second tower casts a shadow of length 140 m, find its height? - 80 m
- 84 m
- 88 m
- 90 m
The Correctoption is(B)
Let the height of the second tower = X We know that the length of the shadow is directly proportional to the height of the tower. X = 84 m (Option B)
