Let C and D be the position of the aeroplanes.
Given that CB = 900 m,∠CAB = 60°,∠DAB = 45°
From the right △ ABC,
Tan45 = CB/AB => CB = AB
From the right △ ADB,
Tan30 = DB/AB => DB = ABtan30 = CBx(1/√3) = 750/√3
CB = CD + DB
=> Required height CD = CB - DB = 750 - 750/√3 = 250(3 - √3)

7 × 57 + 7 × 65 = 854
Since the 7th number came twice, it is added two times.
So the answer = 854 – 13 × 60 = 74
Hence, Option D is correct.

TCP stands for Transmission Control Protocol.

Key Points

• The Transmission Control Protocol (TCP) is a transport protocol built on top of IP that ensures packet delivery reliability.
• In Transmission Control Protocol communication, the two computers begin by establishing a connection via an automated process called a ‘handshake.’
  • Once this handshake is complete, the first computer will begin delivering data packets to the second.
• TCP addresses many of the issues that arise with packet-based messaging, such as missing packets, out-of-order packets, duplicate transmissions, and malformed packets.
• TCP communications specify the order in which data packets should be received and verify that they arrive in the correct sequence.
• TCP specifies that if a packet does not arrive (due to congestion in intermediary networks) it be resent.

Additional Information

Eight students Kirti, Ayushi, Manu, Sona, Aarti, Bobby, Ankita and Divya are sitting around the square table.

Four students sit on each side while rest on each corner.

Students at the side face away from the centre and students at the corner faces towards the centre.

Inferences:

So, we need to arrange as follows to accommodate the information as stated in the question,

References:

Divya sits third to the left of Ayushi.

Kirti sits opposite to Manu and both faces away from the centre.

Inferences:

From the above references, we get the following two different cases:

Case 1:

Case 2:

Explanation:
The correct statement is C: India's annual increase in population is not enough to neutralize efforts to conserve the resource endowment and environment.
Reasoning:
- Statement A: India has a very large population - This is correct as India is currently the second-most populous country in the world.
- Statement B: When a low annual rate is applied to a very large population, it yields a large absolute increase - This is correct as even a small percentage increase in a large population can result in a significant absolute increase.
- Statement D: None of the above - This is not the correct answer, as there is one statement that is incorrect.
Statement C is incorrect because efforts to conserve the resource endowment and environment can be neutralized if the annual increase in population is high and puts a strain on resources. However, the statement suggests that the annual increase in population is not enough to neutralize these efforts, which is not true.
Therefore, the correct answer is C: India's annual increase in population is not enough to neutralize efforts to conserve the resource endowment and environment.

Let AB be the observer and CD be the tower.

Draw BE ⊥ CD.

Then, CE = AB = 1.6 m,

BE = AC = 20√3 m.

∴ CD = CE + DE = (1.6 + 20) m = 21.6 m.
