| W | 70 | 90 | 50 | 85 |
| X | 55 | 80 | 95 | 60 |

The given table represents the marks obtained by four students W, X, Y and Z in four subjects P, C, B and M, with the maximum marks in each subject being 100.
The student who got the highest percentage of marks in P, C, M and B combined is:
To find the student with the highest percentage of marks in P, C, M, and B combined, we need to calculate the total marks obtained by each student across all four subjects and then determine their overall percentage. Since the maximum marks in each subject are 100, the total maximum marks for four subjects will be 400. The percentage for each student will be their total marks divided by 400, multiplied by 100.
D) W — Student W has the highest total marks (295) and therefore the highest combined percentage (73.75%).
The problem presents a pair of numbers (1990 : 1394) and asks us to find a missing number that has a similar relationship with 2017. We need to identify the pattern or operation that transforms the first number into the second number in the given pair and then apply the same pattern to 2017 to find the missing number.
C) 2613 — Based on the identified pattern where the second number is obtained by subtracting 596 from the first number, applying this to 2017 (by adding 596 to 2017) gives 2613.
The question asks to identify the state where Gumthala Garhu village became the first Wi-Fi hotspot village under BSNL's bulk plan. This is a factual question related to current affairs or general knowledge about digital infrastructure initiatives in India.
Correct Option: C) Haryana is the state where Gumthala Garhu village, near Pehowa in Kurukshetra district, became the first Wi-Fi hotspot village under BSNL's bulk plan. This initiative was part of the government's efforts to boost digital connectivity in rural areas.
The question asks about the purpose behind the launch of Bengaluru's city logo in 2017. This is a factual question related to current affairs and urban branding initiatives.

Correct Option: B) The circle and diagonal line align correctly when folded.
The question asks to identify the specific badminton tournament won by Indian shuttler Siddharth Pratap Singh in Uppsala, Sweden, in 2018. This requires knowledge of sports current events, specifically junior international badminton tournaments.
B) The 2018 Swedish Open Junior International — Siddharth Pratap Singh won the 2018 Swedish Open Junior International title in Uppsala, Sweden, by defeating Denmark's Mads Christophersen in the finals with scores of 21-15, 21-11. The location "Uppsala" is a key indicator for the Swedish Open.
The question asks to identify the specific event that marks the onset of puberty in females. This requires understanding the definitions of the terms provided in the options related to the female reproductive cycle and development.
Correct Option: C) Menarche is the first menstrual period, which is the definitive physiological sign marking the onset of puberty in females. It indicates that the female reproductive system has matured enough to begin the menstrual cycle.
Select the option that represents the number of triangles in the given figure.
To determine the number of triangles in the given figure, we need to systematically count all the possible triangles formed by the intersecting lines within the circle.
Thus, the total number of triangles is 7.
Correct Option: D) 7
The question asks to identify the southernmost tip of South America where the Pacific and Atlantic oceans converge. This requires knowledge of world geography, specifically the prominent capes and their locations.
Correct Option: D) Cape Horn is the southernmost tip of the continent of South America, located in Chile, where the Pacific and Atlantic oceans converge. It is infamous for its rough seas and strong winds.
Pipes A, B and C are attached to an empty cistern. While the first two can fill the cistern in 4 and 10 hours, respectively, the third can drain the cistern in 6 hours. If all the three pipes are opened simultaneously when the cistern is half-full, how many hours will be needed to fill the cistern?
\( \frac{90}{11} \)
\( \frac{30}{11} \)
\( \frac{60}{11} \)
\( \frac{120}{11} \)
This problem involves calculating the combined work rate of multiple pipes (fillers and drainers) to determine the time required to fill a cistern. We will first find the individual filling/draining rates, then the net rate when all pipes are open, and finally use this net rate to calculate the time needed to fill the remaining half of the cistern.
Pipe A fills the cistern in 4 hours. So, in 1 hour, Pipe A fills:
\[ \text{Rate of A} = \frac{1}{4} \text{ of the cistern} \]Pipe B fills the cistern in 10 hours. So, in 1 hour, Pipe B fills:
\[ \text{Rate of B} = \frac{1}{10} \text{ of the cistern} \]Pipe C drains the cistern in 6 hours. So, in 1 hour, Pipe C drains:
\[ \text{Rate of C} = \frac{1}{6} \text{ of the cistern} \]The net rate is the sum of filling rates minus the draining rate.
\[ \text{Net Rate} = \text{Rate of A} + \text{Rate of B} - \text{Rate of C} \]\[ \text{Net Rate} = \frac{1}{4} + \frac{1}{10} - \frac{1}{6} \]To add/subtract these fractions, find a common denominator, which is 60.
\[ \text{Net Rate} = \frac{15}{60} + \frac{6}{60} - \frac{10}{60} \]\[ \text{Net Rate} = \frac{15 + 6 - 10}{60} = \frac{21 - 10}{60} = \frac{11}{60} \text{ of the cistern per hour} \]The cistern is already half-full. So, the remaining portion to be filled is:
\[ \text{Remaining portion} = 1 - \frac{1}{2} = \frac{1}{2} \text{ of the cistern} \]Time = (Remaining portion) / (Net Rate)
\[ \text{Time} = \frac{1/2}{11/60} \]\[ \text{Time} = \frac{1}{2} \times \frac{60}{11} \]\[ \text{Time} = \frac{30}{11} \text{ hours} \]Correct Option: B) \( \frac{30}{11} \)
