Question : A person covers a certain distance by bus at 45 km/hr and immediately returns to the starting point by car at a speed of 80 km/hr. What is his average speed during the whole journey?
Option 1: 57.6 km/hr
Option 2: 63.2 km/hr
Option 3: 73.5 km/hr
Option 4: 45.5 km/hr
Correct Answer: 57.6 km/hr
Solution : Let the total distance travelled by the person during the whole journey be $2x$ km. We know, time = $\frac{\text{Total distance}}{\text{Total time}}$ So, time taken by him to travel $x$ km at a speed of 45 km/hr = $\frac{x}{45}$ Time taken by him to
Question : Comprehension:
Read the passage and answer the questions that follow.
The drainage systems of India are mainly controlled by the broad relief features of the subcontinent. Accordingly, the Indian rivers are divided into two major groups: the Himalayan rivers and the Peninsular rivers. Apart from originating from the two major physiographic regions of India, the Himalayan and the Peninsular rivers are different from each other in many ways. Most of the Himalayan rivers are perennial. It means that they have water throughout the year. These rivers receive water from rain as well as from melted snow from the lofty mountains. The major Himalayan rivers are the Indus, the Ganga and the Brahmaputra. These rivers are long and are joined by many large and important tributaries. A river along with its tributaries may be called a river system. The two major Himalayan rivers, the Indus and the Brahmaputra originate from the north of the mountain ranges. They cut through the mountains making gorges in the upper course. The perennial Himalayan rivers have long courses from their source to the sea. They perform intensive erosional activity in their upper courses and carry huge loads of silt and sand with their swift current. In the middle and the lower courses, these rivers form meanders, oxbow lakes, levees, and many other depositional features in their floodplains as their speed slackens. They also have well-developed deltas. A large number of the Peninsular rivers like the Godavari, Kaveri and Krishna are seasonal, as their flow is dependent on rainfall. During the dry season when it doesn’t rain, even the large rivers have reduced flow of water in their channels. The Peninsular rivers have shorter and shallower courses as compared to their Himalayan counterparts. However, some of them originate in the central highlands and flow towards the west. Most of the rivers of peninsular India originate in the Western Ghats and flow towards the Bay of Bengal.
Question:
Which of these is NOT a Himalayan river?
Option 1: Indus
Option 2: Godavari
Option 3: Ganga
Option 4: Brahmaputra
Correct Answer: Godavari
Solution : The correct choice is the second option.
Explanation: The Godavari is not a Himalayan river. The passage explicitly mentions that the major Himalayan rivers are the Indus, the Ganga, and the Brahmaputra. The Godavari is mentioned separately as one of the peninsular rivers. Therefore, Godavari
Question : Directions: Select the correct mirror image of the given combination when the mirror is placed at PQ as shown below.
Option 1:
Option 2:
Option 3:
Option 4:
Correct Answer:
Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection. Here, according to the information provided, the mirror is placed on the right side of the figure (on line PQ). So, the left side of the reflected image will appear
Question : The inradius of a triangle is 6 cm, and the sum of the lengths of its sides is 50 cm. The area of the triangle (in sq. cm) is:
Option 1: 150
Option 2: 50
Option 3: 300
Option 4: 56
Correct Answer: 150
Solution : The area of a triangle by using the formula involving the inradius ($r$) and the semi-perimeter ($s$) of the triangle. $\text{Area} = rs$ Given that the inradius is 6 cm, the sum of the lengths of its sides is 50 cm, and the semi-perimeter is

Question : If $\cot A = \frac{15}{8}$, then what will be the value of $\tan 2 A ?$
Option 1: $\frac{200}{161}$
Option 2: $\frac{240}{161}$
Option 3: $\frac{240}{173}$
Option 4: $\frac{220}{171}$
Correct Answer: $\frac{240}{161}$
Solution : $\cot A = \frac{15}{8}$ So, $\tan A = \frac{8}{15}$ Now, $\tan 2A = \frac{2 \ tan A}{1-\tan^2A}$ = $\frac{2 \times \frac{8}{15}}{1-(\frac{8}{15})^2}$ = $\frac{\frac{16}{15}}{\frac{161}{225}}$ = $\frac{16 \times 225}{15 \times 161}$ = $\frac{240}{161}$ Hence, the correct answer is $\frac{240}{161}$.
