Correct answer is option 'A'. Can you explain this answer?

Bluehawk answered  •  23 hours ago
Well, I think you must be confused between the options 'is' and 'are'. If that's the case, let me explain why 'is' is correct and not 'are'.
Here, 'Politics' is a singular word since it is not a group of things that it would be plural (and you know politics is just one large subject), hence, it will be considered as a singular word. Hence, we use 'is', and not 'are'.

  • d)
    Sri Lanka was declared a secular state
Correct answer is option 'D'. Can you explain this answer?

Flembe Academy answered  •  2 days ago
Option 4: Sri Lanka was declared a secular state is the action that was not taken by the government in 1956 in Sri Lanka. In fact, after the 1956 elections, the Sri Lankan government took a series of steps to promote Sinhala nationalism and Buddhism, including:
  1. Passing the Sinhala Only Act in 1956, which recognized Sinhala as the only official language of Sri Lanka and replaced English.
  2. Implementing preferential policies that favored Sinhala applicants for university positions and government jobs.
  3. Enshrining the protection and fostering of Buddhism in the constitution.
As a result of these actions, Sri Lanka's minority Tamil population, which had traditionally been favored by the British colonial authorities, began to feel marginalized and discriminated against by the Sinhalese-dominated government. This eventually led to a protracted civil war between the government and Tamil separatist groups, which lasted for over 25 years and resulted in significant loss of life and property.

Correct answer is option 'B'. Can you explain this answer?

Kuldeep Kaur answered  •  3 days ago
Let's denote the radius of the hemisphere and the cone as r. Since the diameter of the base of the conical portion is 6 cm, we have:

r = 6/2 = 3 cm

Now, let's find the slant height of the cone. We can use the Pythagorean theorem to find it:

l = √(r^2 + h^2) = √(3^2 + 4^2) = √(9 + 16) = √25 = 5 cm

The surface area of the cone is given by the formula:

The mean of the marks obtained by 7 students in a group is 226. If the marks obtained by six of them are 340, 180, 260, 56, 275, 307, then the marks obtained by the seventh student are​
  • a)
    200
  • b)

  • c)
    174
  • d)
    164
Correct answer is option 'D'. Can you explain this answer?

Manmohan Singh answered  •  3 days ago
Let the marks of the seventh student be x.

The mean of the marks obtained by 7 students is 226, so the total marks of the 7 students is 226 * 7 = 1582.

The sum of the marks obtained by the six students is 340 + 180 + 260 + 56 + 275 + 307 = 1418.

So, the marks obtained by the seventh student are 1582 - 1418 = 164.

Therefore, the answer is (d) 164.
