IT Trainer Questions

Entropy is a measure of disorder . It will be maximum in gases followed by liquids and least in solids.

Hence, here the gas is only hydrogen and it has the highest entropy.

Speeds of two trains = 30 kmph and 58 kmph

=> Relative speed = 58 - 30 = 28 kmph = 28 x 5/18 m/s = 70/9 m/s

Given a man takes time to cross length of faster train = 18 sec

Now, required Length of faster train = speed x time = 70/9  x  18 = 140 mts.

A worksheet or sheet is a collection of cells in a file created with an electronic spreadsheet program such as Microsoft Excel or Google Sheets where we can keep and save data.

Here in a worksheet, we can select a single row or column or multiple rows or columns or we can select the entire worksheet. We can create multiple worksheets in a workbook.

Here it is asked that 3 is what percent of 5

Let 3 is K percent of 5.

=> K x 5/100 = 3

=> K = 300/5 = 60

Hence, 3 is 60% of 5.

Structural Testing is the other name for White Box Techniques.

Except pineapple remaining all three are types of apples.

Pineapple is what kind of apple isn't an apple.

In networking, the Open Systems Interconnection is commonly called as OSI model. It has a 7 layer architecture for the communication.

In OSI network architecture, the routing is performed by network layer which is layer number 3 with the help of intermediate routers.

Let the three numbers be x, y, z.

From the gien data,

x = 2y ....(1)

x = z/2 => z = 2(2y) = 4y .....(From 1)  ...........(2)

Given average of three numbers = 56

Then,

$$\begin{gathered} x + y + z3 = 56 \\ 2y + y + 4y3 = 56 (From 1 & 2) \\ 7y = 56 x 3 \\ y = 24 \end{gathered}$$

Now,

x = 2y => x = 2 x 24 = 48

z = 4y = 4 x 24 = 96

Now, the highest number is z = 96 & smallest number is y = 24

Hence, required sum of highest number and smallest number

= z + y

= 96 + 24

= 120.
