A) 40 cm B) 150 cm
C) 120 cm D) 45 cm
 
Answer & Explanation Answer: B) 150 cm

Explanation:

Let the heights of Cat, Table and Turtle be C, T & R respectively.

 

From the above given figure,

 

C + T - R = 170 ......(a)

 

R + T - C = 130 ......(b)

 

Adding above eqns (a) & (b), we get

 

2T = 300

 

T = 150 cm

 

Hence, the height of the table is 150 cm.

Q:

main()

{

float me = 1.1;

double you = 1.1;

if(me==you)

printf("yes");

else

printf("No");

}

A) Yes B) No
C) Both D) Compilation error
 
Answer & Explanation Answer: B) No

Explanation:

For floating point numbers (float, double, long double) the values cannot be predicted exactly. Depending on the number of bytes, the precession with of the value represented varies. Float takes 4 bytes and long double takes 10 bytes. So float stores 0.9 with less precision than long double.

Q:

Permanent Hardness of water can be removed by adding

A) Bleaching powder B) Chlorine
C) Wasshing soda D) Potassium permanganate
 
Answer & Explanation Answer: C) Wasshing soda

Explanation:

Hardness can be removed by adding sodium carbonate (washing soda) or by passing the water through an ion-exchange column.

 

Hardness in water is caused by dissolved magnesium ions and calcium ions. These can get into the water when it comes into contact with limestone and other rocks that contain calcium compounds. This can happen, for example, when rainwater flows over these rocks on its way to a reservoir.

 

Hardness in water is of two types. They are :

1. Temporary hardness

2. Permanent hardness

 

1. Temporary hardness:: Temporary hardness is caused by dissolved calcium hydrogen carbonate.


2. Permanent hardness:: Permanent hardness is caused by dissolved calcium sulfate. Unlike temporary hardness, it is not removed by boiling the water.

Q:

Which of the following is not a static testing technique?

A) Inspections B) Data flow analysis
C) Error guessing D) Walkthrough
 
Answer & Explanation Answer: C) Error guessing

Explanation:

Static Testing, a software testing technique in which the software is tested without executing the code. This Techniques provide a powerful way to improve the quality and productivity of software development by assisting engineers to recognize and fix their own defects early in the software development process.

 

It has two parts as listed below:

Review - Typically used to find and eliminate errors or ambiguities in documents such as requirements, design, test cases, etc.

Static analysis - The code written by developers are analysed (usually by tools) for structural defects that may lead to defects.

 

In this software is tested without executing the code by doing Review, Walk Through, Inspection or Analysis etc.

 

Hence, Error guessing is not a static software testing technique.
