The given passage tells us that we should use our speech carefully.
Let's refer to the passage: "A slip of the tongue, the use of an unusual word, or of an ambiguous word, and so on, may create an enemy where we had hoped to win a friend."
From this line, we can understand that using an ambiguous word may create an enemy for us where he had wanted to make a friend.
So, to win a friend, we should avoid ambiguity in speech.
Hence, option 3 is the correct answer.

Given the context of different classes of people having different vocabularies, the passage says, "Unwittingly, we may use a word which bears a different meaning to our listener from what it does to mean of our class." This suggests that the words and phrases familiar and ordinary to one group might be unfamiliar and even off-putting to another.

So, when the question asks, "While talking to an uneducated person, we should use," the answer " (খ) simple words" makes the most sense. Using simpler words reduces the risk of sounding pompous or confusing the listener.

The other options:

ক) ordinary speech: This might not be effective, as the passage states that the ordinary speech of an educated person might sound pompous to an uneducated listener.
গ) polite language: While politeness is always appreciated, the passage's main focus is on the clarity and simplicity of speech rather than the politeness of it.
ঘ) his vocabulary: This could be misinterpreted. Trying to mimic or adopt the exact vocabulary of another person might come off as condescending or inauthentic.
Given the context and emphasis on clear communication, "simple words" (খ) is the best option for speaking to an uneducated person as per the passage.

The given passage tells us that we should use our speech carefully.
Let's refer to the passage: "Only a fool will express himself alike to all kinds and conditions of men."
From this line, we can understand that if we express ourselves in the same style to all kinds of men, we will sound foolish.
Hence, option 1 is the correct answer.

The second sentence of the passage says "A slip of the tongue, the use of an unusual word, or of an ambiguous word, and so on, may create an enemy where we had hoped to win a friend''.
A ''slip of the tongue'' means a speech mistake in which a phrase is pronounced wrongly or something is said accidentally or unintentionally by the speaker.
From the above explanation, we can say that the phrase ''a slip of the tongue'' in the passage means 'something said unintentionally'.

The given passage tells us that we should use our speech carefully.
The first sentence of the passage says "Speech is a great blessing but it can also be a great curse, for while it helps us to make our intentions and desires known to our fellows, it can also if we use it carelessly, make our attitude completely misunderstood''.
From the above sentence, we can say that speech can be a curse because it can create misunderstanding.
Hence, the only possible answer is option 4.

Since we know that, Speed=Distance/Time
In order to find time, we use the following,
Time=Distance/Speed
So the distance between two buses is 300 km, let bus A speed be 38 km per hr and speed of bus B be 37 km per hr.
Therefore, Time=300/38+37
Thus on solving the above we get the answer as 4hrs.

Let the rate be R%p.a.
Then,
5000 × R × 2/100 + 3000 × R × 4/100 = 2200.
⇒ 100R + 120R = 2200
⇒ R = 2200/220 =10
∴Rate = 10%

Let,
Speed = x km/h
So,
40x - 40x × (14/15) = 5
Or, 40x - 112x/3 = 5
Or, 120x - 112x = 15
Or, x = 15/8
∴ distance covered = (15 × 40)/8 = 75 km

Let man's rate upstream be x kmph
Then, his rate downstream = 2x kmph
∴ (speed in still water) : (Speed of stream)
=(2x+x)/2 : (2x−x)/2
= 3x/2 : x/2 = 3 : 1

At 5% discount for the first time = 80 × 95/100 = Tk. 76 
At 5% discount for second time = 76 × 95/100 = Tk. 72.20

Let V liters of 90% of conc acid is required to mix
Now to get 30 liters of 78% of conc acid solution we have total volume of solution = 30 liters
(30- v) liters of 75% of another conc acid to be mixed

Now we have
N₁V + N₂(30- V) = N × 30
90 × V + 75 × (30- V) = 78 × 30
V = 6 liters

Volume of the block = (6 × 12 × 15) cm³
= 1080 cm³
Side of the largest cube
= H.C.F of 6 cm, 12 cm, 15 cm
= 3 cm.
Volume of this cube = (3 × 3 × 3) cm³
= 27 cm³
Number of cubes = 1080/27
= 40.

We have: (l - b) = 23 and 2(l + b) = 206 or (l + b) = 103
Solving the two equations, we get: l = 63 and b = 40
∴ Area = (l x b) = (63 x 40) m² = 2520 m²

Time taken by one tap to fill half the tank = 3 hrs.
Part filled by one tap in 1 hour = 1/6
Part filled by four taps in 1 hour = (4×1/6) = 2/3
Remaining part = (1−1/2) = 1/2
2/3 of the tank is filled by four taps in 1 hour.
So, 1/2 of the tank is filled in = 3/2×1/2=3/4 hours
3/4 hours = 3/4 × 60 = 45 min
So, the total time taken = 3 hrs + 45 min = 3 hrs 45 min or 225 min
-------------------------------------------------
Alternative way:
A tap can fill a tank in 6 hours.
A tap can fill half of a tank in 6/2 or 3 hours.
4 tap can fill half of a tank in 3/4 hours = 45 min
Total time taken = 3 hours 45 min

(m+n)/(m−n) = 7x/x
⇒ m/n=4x/ 3x  
Again   mn=12x²
and mn =60x
so, 60x=12x²
⇒ x = 5
=>  m = 20  and n= 15
Hence,    1/m : 1/n = 1/20 : 1/15 = 3 : 4

√(0.01 + √0.0064)

Information is the product of data processing.

- A GUI (graphical user interface) is a system of interactive visual components for computer software.
A GUI displays objects that convey information, and represent actions that can be taken by the user.
The objects change color, size, or visibility when the user interacts with them.
- GUI objects include icons, cursors, buttons. These graphical elements are sometimes enhanced with sounds or visual effects like transparency and drop shadows.
- A GUI is considered to be more user-friendly than a text-based common line interface, such as MS-DOS, or the shell of Unix-like operating systems.
