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:
‘Perennial’ rivers mean:
Option 1: receiving water from the rains
Option 2: those that originate in the mountains
Option 3: rivers with a long course
Option 4: full of water throughout the year
Correct Answer: full of water throughout the year
Solution : The correct choice is the fourth option.
Explanation: The passage mentions that perennial rivers, such as most of the Himalayan rivers (Indus, Ganga, and Brahmaputra), are rivers that have water throughout the year. This means they are not dependent solely
Question : A certain sum of money amounts to Rs. 918 in 2 years and Rs. 969 in 3.5 years at simple interest. What is the rate of interest (in percent per year)?
Option 1: 4
Option 2: 5
Option 3: 6
Option 4: 8
Correct Answer: 4
Solution : Interest for 1.5 years = 969 - 918 = Rs. 51 i.e. 1 year interest = $\frac{51}{1.5}$ 1 year interest = Rs. 34 Now Rs. 918 contains interest of Rs. 34 for two years (i.e. two times) The principal amount is Rs. 918 – (Rs.
Question : Directions: In the following question, some parts of the sentence may have errors. Find out which part of the sentence has an error and select the appropriate option. If the sentence is free from error, select "No Error".

Question : In an examination, the number of students who passed and the number of students who failed were in the ratio 25 : 4. If one more student had appeared and passed and the number of failed students was 3 less than earlier, the ratio of passed students to failed students would have become 22 : 3. What is the difference between the number of students who, initially, passed the examination and the number of students who failed the examination?
Option 1: 132
Option 2: 126
Option 3: 174
Option 4: 150
Correct Answer: 126
Solution : Let the initial number of students who passed be $25x$ and the number of students who failed be $4x$, where $x$ is a constant. If one more student had appeared and passed and the number of failed students was 3 less than earlier, the ratio
Question : A solid cylinder has a radius of base of 14 cm and a height of 15 cm. Four identical cylinders are cut from each base, as shown in the given figure. The height of a small cylinder is 5 cm. What is the total surface area (in cm2) of the remaining part?
Option 1: 3740
Option 2: 3432
Option 3: 3124
Option 4: 2816
Correct Answer: 3432
Solution : Radius of larger cylinder, $r$ = 14 cm and height, $h$= 15 cm Radius of smaller cylinders, $r_1$ = $\frac{28}{8}$ = $\frac{7}{2}$ cm and height, $h_1$ = 5 cm The curved surface area of the remaining part = $2\pi rh+8×2\pi r_1 h_1$ ($\because$ There are
Question : Directions: Three of the following four-letter clusters are alike in a certain way and one is different. Pick the odd one out.
Option 1: EUT
Option 2: RHG
Option 3: TRQ
Option 4: TFE
Correct Answer: TRQ
Solution : Let's check each option – First option: EUT; The opposite pair of E is V and V – 1 = U and U – 1 = T Second option: RHG; The opposite pair of R is I and I – 1 = H and H
Question : Directions: In a certain code language, ENGINE is written as ENIGNE, and TRAIN is written as NIART. How will LEVEL be written in that language?
Option 1: LEELV
Option 2: LEVEL
Option 3: LEEVL
Option 4: LELEV
Correct Answer: LEVEL
Solution : Given: ENGINE is written as ENIGNE, and TRAIN is written as NIART.
Reverse the letters of the words to obtain the required code. ENGINE→ENIGNE Thus, ENGINE is coded as ENIGNE. TRAIN→NIART Thus, TRAIN is coded as NIART. Similarly, LEVEL→LEVEL
So, LEVEL is coded as LEVEL
