Question : Directions: Suman drives 3 km towards north from point A. She takes a right turn and drives 4 km more. Then she takes another right turn and drives 3 km. Finally, she takes one more right turn and drives 6 km to reach point B. How far and towards which direction should she drive to reach point A again?
Option 1: 2 km towards the south
Option 2: 3 km towards the north
Option 3: 3 km towards the west
Option 4: 2 km towards the east
Correct Answer: 2 km towards the east
Solution : First, we will draw the diagram, as per the given instructions –
Here, A is the starting point and B is the end point.
To reach point A again from B, Suman should drive 2 km towards the East. Hence, the
Question : If $(\frac{\sec \theta-1}{\sec \theta+1})^n=\operatorname{cosec} \theta-\cot \theta$, then $n=?$
Option 1: 1
Option 2: 0.5
Option 3: –1
Option 4: –0.5
Correct Answer: 0.5
Solution : Given expression, $(\frac{\sec \theta-1}{\sec \theta+1})^n=\operatorname{cosec} \theta-\cot \theta$ Considering L.H.S., We know, $\sec\theta=\frac{1}{\cos\theta}$ = $\left\{\frac{\frac{1}{\cos\theta}-1}{\frac{1}{\cos\theta}+1}\right\}^n$ = $\left\{\frac{1-\cos\theta}{1+\cos\theta}\right\}^n$ Multiplying and dividing by $1-\cos\theta$, we get, = $\left\{\frac{1-\cos\theta}{1+\cos\theta}\times\frac{1-\cos\theta}{1-\cos\theta}\right\}^n$ = $\left\{\frac{(1-\cos\theta)^2}{1-\cos^2\theta}\right\}^n$ = $\left\{\frac{(1-\cos\theta)^2}{\sin^2\theta}\right\}^n$ Now consider R.H.S, $\operatorname{cosec} \theta-\cot \theta$ We know, $\operatorname{cosec} \theta=\frac{1}{\sin\theta}$ and $\cot\theta=\frac{\cos\theta}{\sin\theta}$ = $\frac{1}{\sin\theta}-\frac{\cos\theta}{\sin\theta}$ = $\frac{1-\cos\theta}{\sin\theta}$
Question : In a survey, 200 respondents were asked whether they owned a vehicle or not. Their responses are tabulated below. What percentage of respondents do NOT own a car?
Option 1: 68.5%
Option 2: 75%
Option 3: 65%
Option 4: 72.5%
Correct Answer: 72.5%
Solution : Given: In a survey, 200 respondents were asked whether they owned a vehicle or not. The percentage of respondents who do not own a car $=\frac{\text{Total respondents who do not own a car}}{\text{Total respondents}}×100=\frac{30+50 + 20 + 45}{200}\times 100=\frac{145}{200}=72.5\%$ Hence, the correct answer is 72.5%.
Question : Directions: Select the related letter cluster from the given alternatives. GDM : ROX :: AOP : ?
Option 1: MZA
Option 2: LAB
Option 3: LZA
Option 4: MBA
Correct Answer: LZA
Solution : Given: GDM : ROX :: AOP : ?
Add 11 to the place value of each letter of GDM to obtain the required code – G + 11 = R; D + 11 = O; M + 11 = X Thus, GDM is coded as
Question : Which cell organelle appears as rounded or sausage-shaped structures under electron microscopy, measuring about 0.5-1.0 μm in diameter and 2-8 μm in length?
Option 1: Ribosomes
Option 2: Lysosomes
Option 3: Mitochondria
Option 4: Plastids
Correct Answer: Mitochondria
Solution : The correct answer is Mitochondria.
The cell organelle that appears as rounded or sausage-shaped structures under electron microscopy, measuring about 0.5–1.0 μm in diameter and 2–8 μm in length, is the mitochondrion. Mitochondria are responsible for energy production within the cell through the process of
