Question : Two men are on opposite sides of a tower. They measure the angles of elevation of the top of the tower as 30° and 45°, respectively. If the height of the tower is 50 metres, the distance between the two men is: (take $\sqrt{3}=1.732$)
Option 1: $136.6$ metres
Option 2: $50\sqrt{3}$ metres
Option 3: $100\sqrt{3}$ metres
Option 4: $135.5$ metres
Correct Answer: $136.6$ metres
Solution : Let the positions of the two men be A and B. Let PQ represent the tower. $\angle$QAP = 30° and $\angle$QBP = 45° QP = 50 m We get two right-angled triangles △QPB and △QPA Now, From the △QPA: tan 30° = $\frac{PQ}{AP}$ ⇒$\frac{1}{\sqrt{3}}=\frac{50}{AP}$
Question : Directions: A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in the two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. P can be represented by 55,69, etc, and L can be represented by 59, 68, etc. Similarly, you have to identify the set for the word, LAPSE.
Option 1: 86, 02, 55, 14, 97
Option 2: 86, 57, 00, 41, 97
Option 3: 31, 02, 00, 96, 42
Option 4: 31, 57, 55, 41, 42
Correct Answer: 86, 02, 55, 14, 97
Solution : Given: LAPSE
Number representations of each letter – L→59, 68, 77, 86, 95 A→02, 11, 20, 34, 43 P→55, 69, 78, 87, 96 S→00, 14, 23, 32, 41 E→56, 65, 79, 88, 97
Let's check the options – First option: 86,
Question : The speed of a boat in standing water is 6 km/hr and the speed of the stream is 2.5 km/hr. A man rows to a place at a distance of 59.5 kilometres and comes back to the starting point. The total time taken by him is:
Option 1: 16 hours
Option 2: 24 hours
Option 3: 22 hours
Option 4: 18 hours
Correct Answer: 24 hours
Solution : The total time taken by the man can be calculated by adding the time taken to row downstream (with the current) and the time taken to row upstream (against the current). The effective speed of the boat while going downstream (with the current) is
Question : Directions: Select the related letter cluster from the given alternatives. BDCE : FHGI :: RTSU : ?
Option 1: VYWX
Option 2: XYVW
Option 3: VWXY
Option 4: VXWY
Correct Answer: VXWY
Solution : Given: BDCE : FHGI :: RTSU : ?
Here, add 4 to the place value of each letter of BDCE to obtain the required code – B + 4 = F; D + 4 = H; C + 4 = G; E + 4 =

Question : Chords $\overline{AB}$ and $\overline{CD}$ of a circle intersect inside the circle at point F. If $m(\overline{AF})=2.4$ cm, $m(\overline{BF})=1.8$ cm and $m(\overline{CD}) = 5.7$ cm, what is the length (in cm) of the longer of the two line segments, $\overline{CF}$ and $\overline{DF}$?
Option 1: 4.5
Option 2: 4.8
Option 3: 5.4
Option 4: 3.6
Correct Answer: 4.8
Solution : $m(\overline{AF}) = 2.4$ cm $m(\overline{BF}) = 1.8$ cm $m(\overline{CD}) = 5.7$ cm Let CF = $x$ cm DF = ($5.7-x$) cm Since AB and CD are two chords of a circle that intersect at point F, AF × BF = CF × DF ⇒ 2.4
