Calculate the number of sleepers required for constructing a railway t...
Given:
For BG track, length of rail = 12.8 m [General information]
∴ n = 13 [next positive integer of 12.8]
Number of sleepers per rail length = M + 5
So,
Number of sleepers per rail length = 13 + 5 = 18
Number of rails = 640/12.8 = 50
So number of sleepers needed = 50 × 18 = 900

Calculate the number of sleepers required for constructing a railway t...
To calculate the number of sleepers required for constructing a railway track, we need to consider the length of the track and the sleeper density.

Given:
Length of the track = 640 m
Sleeper density = M

To calculate the number of sleepers required, we can use the formula:

Number of sleepers = Length of the track / Sleeper density

Let's calculate the number of sleepers required using the given values:

Number of sleepers = 640 m / M

Since the value of M is not given, we cannot directly calculate the number of sleepers required. However, we can determine the value of M by using the given options.

Given options:
a) 600
b) 300
c) 900
d) 50

To find the correct value of M, we need to check which option satisfies the given condition:

Number of sleepers = 640 m / M

Let's substitute each option into the formula and check which one gives a whole number as the result:

a) Number of sleepers = 640 m / 600 = 1.0667 (not a whole number)
b) Number of sleepers = 640 m / 300 = 2.1333 (not a whole number)
c) Number of sleepers = 640 m / 900 = 0.7111 (not a whole number)
d) Number of sleepers = 640 m / 50 = 12.8 (not a whole number)

None of the given options gives a whole number as the result. Therefore, none of the options is the correct answer.

It seems that there might be an error in the question or the given options. Without the correct value of M, we cannot accurately calculate the number of sleepers required.
