The correction to be applied to each 30 metre chain length along θ slope , is
Correct Answer :- C
Explanation : Actual slope correction is always -ve therefore,
Correction = - [L(1 - cosθ)].
= (Lcosθ - L).
= L(cosθ - 1) ; now L is 30m chain.
So the answer comes out to be = 30(cosθ - 1) m.

The maximum number of vehicles that can be parked in a given space depends on the type of parking configuration used. Here's a brief explanation of each parking configuration and their capacity:
1. Parallel parking: In this configuration, vehicles are parked parallel to the curb or the parking boundary. This type of parking generally takes up the most space per vehicle, and the number of vehicles that can be parked depends on the length of the parking space and the size of the vehicles.
2. 30º angle parking: In this configuration, vehicles are parked at a 30-degree angle to the curb or the parking boundary. This type of parking allows for more vehicles to be parked in a given space compared to parallel parking, as it requires less space per vehicle. However, it still takes up more space than 45º or 90º angle parking.
3. 45º angle parking: In this configuration, vehicles are parked at a 45-degree angle to the curb or the parking boundary. This type of parking allows for even more vehicles to be parked in a given space compared to 30º angle parking, as it requires less space per vehicle. It is a common parking configuration in parking lots and on some streets.
4. 90º angle parking: In this configuration, vehicles are parked perpendicular to the curb or the parking boundary. This type of parking allows for the maximum number of vehicles to be parked in a given space, as it requires the least amount of space per vehicle. It is the most space-efficient parking configuration and is commonly used in parking lots and garages.
In conclusion, the maximum number of vehicles that can be parked in a given space is achieved with 90º angle parking, as it is the most space-efficient configuration. However, the actual number of vehicles that can be parked will depend on the size of the parking area and the size of the vehicles being parked.

IS code recommends that the slope of stairs should be between
The pitch of the stairs should match with the French theory the labour of moving vertically is about twice that of moving horizontally if the average human stride is taken as 23 inches.
If the rise and going are measured in inch units, the best pitch of the stairs is that is that inclination which by twicing the rise and adding the going equals 23. When measured in cm units a comfortable slope a achieved when twice rise plus going is equal to 60 approximately.
In general, the slope of stair should never exceed 40° and be flatter than 25°.
