Question Discussion & Solution

Five friends: A, C, F, U and Z.

1) F is shorter than A who is shorter than Z.

F < A < Z

2) C is shorter than F but not as shorter as U.

This means U is shorter than C.

U < C < F

Combining 1) and 2), we get:

U < C < F < A < Z

The correct answer is Mansagar Lake.

• Jal Mahal is situated in the middle of Mansagar Lake.

Key Points

• Jal Mahal literally means the “Water Palace”, but when it was built, Maharaja Madho Singh I did not intend to use it as a palace.

• Mansagar Lake
  • Man Sagar Lake is an artificial lake, situated in Jaipur.
  • It is named after Raja Man Singh, the then ruler of Amer, who constructed it in c. 1610 by damming the Dravyavati river.
  • The Jal Mahal is situated in the middle of the lake.

Additional Information 

• Kayalana Lake
  • Kaylana Lake is located 8 km west of Jodhpur.
  • It is an artificial lake, built by Pratap Singh in 1872. 
• Foy Sagar Lake 
  • ​Lake Foy Sagar is an artificial lake situated near Ajmer.

The correct answer is Open Cast Mining.

• Open Cast Mining is the process under which minerals are mined near the earth's surface.

Key Points

• Opencast mining is the process that involves the removal of ore from seams relatively near the surface by means of an open-pit.
• These mines occupy a large area of land for excavation of the ore and disposal of the overburden.

Additional Information

• Drilling is a cutting process which uses a drill bit to cut a hole of circular cross-section in solid materials or ground.
• Quarrying is the process of removing rock, sand, gravel or minerals from the ground in order to use them to produce materials for construction or other uses.
• Shaft mining is the process where miners dig straight down until they reach their desired depth. 

The correct answer is "option 2"

CONCEPT:

Structure in C is a user-defined data type that is used to store the collection of different data types.

The total size of the structure is the sum of the size of every data member.

Union is a user-defined data type that is used to store different data types in the same memory location.

The total size of the union is the size of the largest data member.
 

EXPLANATION:

Given the size of short, float and long is 2 bytes, 4 bytes, and 8 bytes, respectively.

Therefore,

Size of Structure → size of ( short s[5] ) + size of Union  

Here, Size of Union = 8 bytes   { largest data member is long }.

Size of short s[5] → 2×5 → 10 bytes

Size of Structure → 10+8 →18 bytes.

Hence, the correct answer is "option 2".

The correct answer is option 1.

Concept:

The auto storage class is the default storage class for all local variables. The variables defined using the auto storage class are called local variables. Auto stands for automatic storage class. A variable is in the auto storage class by default if it is not explicitly specified. The scope of an auto variable is limited to the particular block only.

Storage Classes:

Storage Classes are used to describe the features of a variable/function. These features basically include the scope, visibility, and lifetime which help us to trace the existence of a particular variable during the runtime of a program. C language uses 4 storage classes.

Hence the correct answer is auto.
