A paragraph is a series of sentences that are organized and coherent, and are all related to a single topic. Almost every piece of writing you do that is longer than a few sentences should be organized into paragraphs.
This is because paragraphs show a reader where the subdivisions of an essay begin and end, and thus help the reader see the organization of the essay and grasp its main points.

Previous speed = x
A/Q,
32/x - 32/(x + 4) = 4
Or, 32x + 128 - 32x/x(x + 4) = 4
Or, (x + 4)x = 32
Or, x2 + 4x - 32 = 0
Or, x2 + 8x - 4x - 32 = 0
Or, (x + 8) (x - 4) = 0
So, the previous speed was 4 kmph.
And, Present speed will be 4 + 4 = 8 kmph.
Part filled by A in 1 minute = 1/20
Part filled by B in 1 minute = 1/30
Part filled by (A + B) in 1 minute
= 1/20 + 1/30
= 1/12
∴ Both pipes can fill the tank in 12 minutes
The given equation is:
5/x + 6y = 13 … (a)
3/x + 4y = 7 … (b)
On multiplying (a) by 3, (b) by 5 and subtracting, we get:
-2y = 4
∴ y = -2
প্রশ্নে 3/x + 4 = 7 এর স্থলে 3/x + 4y = 7 হওয়ার কথা ছিলো।

Required average = total sum of multiple of 9/5
= (9 + 18 + 27 + 36 + 45)/5
= 27
Note that, the average of 9 and 45 is also 27.
An average of 18 and 36 is also 27.
AB = BC
⇒ ∠C = ∠A = (2x - 20)°.
∠A+ ∠B + ∠C =180°
⇒ (2x - 20) + x + (2x - 20 ) = 180
⇒ 5x - 40 = 180
⇒ 5x = 220
⇒ x = 44.
∴ ∠B = 44°
Selling price = 50 - (50 × 20%)
= 50 - 10
= 40
Cost Price = (100/100+25) × 40
= (100/125) × 40
= 32
Let, a daughter’s present age be x year.
In that case mother present age would be = 30x years
30x + 18 = 3 (x + 18)
⇒ 27x = 36
⇒ x = 4/3
∴ So the present age of mother = (30 × 4/3)
= 40 years.
30% ক্ষতিতে দাম, 70% = 6384
30% লাভে দাম, 130% = (6384 × 130)/70
= 11856
Let the labeled price of TV = Tk. X
∴ SP of the TV = [X x (100 - 20)]/100
= Tk. 4X/5
But 16,800 - 800 = 4X/5
∴ x = (16,000 x 5)/4
= Tk. 20,000
Principle,
= (P.W. of Tk. 882 due 1 year hence) + (P.W of Tk. 882 due 2 years hence)
= [{882/(1 + 5/100)} + {882/(1 + 5/100)2}]
= [{(882 × 20)/21} + {(882 × 400)/441}]
= Tk. 1640.
sin 30° = 1/2, sin 60° = √3/2, cos 30° = √3/2 and cos 60° = 1/2
Putting these values, we get:
(1/2 + 1/2) - (√3/2 + √3/2)
= 1 – [(2√3)/2]
= 1 – √3
Man walks 20 km in → 5 hours
That means it will take more time to walk 32 km.
This is the case of direct proportion.
20/5 = 32/x
x = 32/4
= 8
The sample space when a dice is rolled, S = (1, 2, 3, 4, 5, and 6)
So, n (S) = 6
E is the event of getting an odd number.
So, n (E) = 3
Probability of getting an odd number P (E) = (Total number of favorable outcomes)/(Total number of outcomes)
n(E)/n(S) = 3/6
= 1/2
Given total sum = Tk. 427
And given that 3 times A’s share, 4 times B’s share and 7 times C’s share are all equal.
=> 3A = 4B = 7C
But given
=> A + B + C = 427
Now express A and B in terms of C i.e
=> (7C/3) + (7C/4) + C = 427
=> C = 84

Researchers from the Netherlands Cancer Institute have discovered a new location of salivary glands in the throat.
In their findings in a research published in the journal Radiotherapy and Oncology, they have named the part as “tubarial glands”. This would be useful for patients with head and neck tumours.
The researchers also believe that these glands would qualify as the fourth pair of major salivary glands.
