Bihar Police Constable Mock Test - 2 - Bihar Police Constable MCQ

Since A, B and C are the angles of a Δ,
∴ A + B + C = 180° .................... (1)
According to question,
A – B = 15° ;
⇒ A = B + 15°...................(2)
B – C = 30°;
⇒ B = C + 30°;....................(3)
Put the value of B from equation (2) in Equation (1), we will get
∴ A = B + 15°
A = C + 30° + 15°
A = C + 45° ......................(4)
From a equation,
∴ A + B + C = 180°
⇒ (C + 45°) + (C + 30°) + C = 180°
⇒ 3C + 45° + 30° = 180°
⇒ 3C = 180° – 75° = 105°
⇒ C = 35° ...........................(5)
From equation (4)
A = C + 45°
Put the value of C from equation (5) , we will get
∴ ∠A = 35° + 45° = 80°.

Option C is correct. The immediate cause of Shahjahan's rebellion against Jahangir was that Shahjahan refused to go to Qandhar, which had been besieged by the Persians.

X × 20 + 40 – 4 = X × 22
36 = 2X
X = 18
Hence, Option A is correct.

Checking Statement I:

Using the above references, we get the information:
 
_ > _ > _ > _ > Tarak > _

Vijay > Komal > Rishi

Here, we cannot merge the above inferences to form a single arrangement of the order of heights of these persons.

So, we cannot say who among these persons is the tallest.

Hence, data in statement I alone is not sufficient.

Checking Statement II:

Using the above references, we get the information:

Rishi > Tarak/Sanjay

So, we cannot say who among these persons is the tallest.

Hence, data in statement II alone is not sufficient.

Checking Statements I and II:

Using the above reference, we get the following arrangement:

Usha > Vijay > Komal > Rishi > Tarak > Sanjay

Clearly, both statements I and II together are sufficient to answer the question.

Hence, Option D is correct.

Thomas Best was an English captain who had sunk four Portuguese ships. This impressed the Mughal Governor and therefore he gave them a treaty which was approved by emperor Jhangir who gave them trading rights.

 

The first English factory in India was established at Surat. However, after four centuries, these early footmarks of the British had been wiped out. There were no remains of a factory or a warehouse. According to historian HG Rawlinson, the factory in Surat was one of the best one. It was a two-storey building. The location was not far from the Surat fort. The fort was said to have been commissioned by Sultan Mahmud III. Surat was one of the most important ports for trading with the Mughals. This port was used by the textile manufacturers of Gujarat. However, the Portuguese were already trading with the Mughals and they were the master of the sea. It would take a lot of time for the British to take over. In 1612, the factory of the East India Company was established in Surat.

Note: In 1611, another factory was established by the East India Company in Masulipatam in Coromandel Coast.in 1626, it extended to the South in Armagaon and settled there because of the availability of cheap cloth. In the main production areas like Gujarat, Bengal and Coromandel, several weavers, washers were employed who worked on muslins, cotton and quilt.

Suraj's rate of work: Suraj can complete the work in 80 days, so his rate of work is 1/80 of the work per day.

Mangal's efficiency: Mangal is 60% as efficient as Suraj. So, Mangal's rate of work will be 60% of Suraj's rate, or (0.60 × 1/80) = 1/133.33 of the work per day.

Combined rate of work: When Suraj and Mangal work together, their combined rate is: (1/80) + (1/133.33).

To add these, we convert them to have a common denominator: (1/80) = 5/400 and (1/133.33) = 3/400.

So, the combined rate is (5/400) + (3/400) = 8/400 = 1/50.

Time taken to complete the work: Since their combined rate is 1/50, they will complete the work in 50 days.

Thus, the answer is 50 days.
