Question : If $\theta$ is an acute angle and $\cos\theta=\frac{11}{17}$, what is the value of $\tan\theta$?
Option 1: $\frac{4 \sqrt{10}}{11}$
Option 2: $\frac{13}{11}$
Option 3: $\frac{2 \sqrt{42}}{11}$
Option 4: $\frac{2 \sqrt{42}}{17}$
Correct Answer: $\frac{2 \sqrt{42}}{11}$
Solution : Given: $\cos\theta=\frac{11}{17}$ Let the Base = 11 units and the Hypotenuse = 17 units We know, $\text{Perpendicular} = \sqrt{(\text{Hypotenuse})^2–(\text{Base})^2}$ So, $\text{Perpendicular} = \sqrt{17^2–11^2}=\sqrt{289–121}=\sqrt{168}=2\sqrt{42}$ units Therefore, $\tan\theta=\frac{\text{Perpendicular}}{\text{Base}}=\frac{2\sqrt{42}}{11}$ Hence, the correct answer is $\frac{2\sqrt{42}}{11}$.
Question : Directions: In the following question below are given some statements followed by some conclusions based on those statements. Taking the given statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusions logically follows the given statements. Statements: I. All D are E. II. Some E are F. Conclusions: I. All D are F. II. Some F is E. III. All E is D.
Option 1: Only conclusion III follows
Option 2: Only conclusion II follows
Option 3: All conclusion follows
Option 4: Only conclusion I follows
Correct Answer: Only conclusion II follows
Solution : The possible Venn diagram according to the given statements is as follows –
Conclusion I: All D are F – From the above diagram, there is no direct relation between D and F. So, this conclusion doesn't follow. Conclusion II: Some F
Question : Directions: A series is given below with one term missing. Choose the correct alternative from the given ones that will complete the series. HK, ?, PQ, TT, XW
Option 1: LN
Option 2: NO
Option 3: LK
Option 4: NM
Correct Answer: LN
Solution : Given: HK, ?, PQ, TT, XW
Add 3, and 4 to the positional value of the first and second letters respectively of the previous term to get the next term in the series. First letter of the series→H + 4 = L; L + 4
Question : Which of the following organisms does not fit into the Cell Theory?
Option 1: Bacteria
Option 2: Virus
Option 3: Fungi
Option 4: Plants
Correct Answer: Virus
Solution : The correct option is the Virus.

Question : Two trains, 180 meters and 120 meters in length, are running towards each other on parallel tracks, one at the rate of 65 km/h and another at 55 km/h. In how many seconds will they be clear of each other from the moment they meet?
Option 1: 6
Option 2: 9
Option 3: 12
Option 4: 15
Correct Answer: 9
Solution : Use: Time taken to cross each other = $\frac{\text{Sum of the lengths of two trains}}{\text{Relative Speed}}$ Speed of 1st train = 65 km/h Speed of 2nd train = 55 km/h They run in opposite directions, therefore, Relative speed = 65 + 55 = 120 km/h
