1. Amina thinks of a number and subtracts 5/2 from it. She multiplies the result by 8. The result now obtained is 3 times the same number she thought of. What is the number?
Solution:
Let the number be x,
According to the question,
(x – 5/2) × 8 = 3x
⇒ 8x – 40/2 = 3x
⇒ 8x – 3x = 40/2
⇒ 5x = 20
⇒ x = 4
Thus, the number is 4.

Given that the price of an article including GST of 18% is Rs.1239
Let the price of the article before GST be x
Therefore, x+18% ofx=1239
⟹x + 18x/ 100=1239
⟹(100x+18x)/100 =1239
⟹118x=1239×100
⟹x=(1239×100)/118=1050
Therefore the price of the article before GST is Rs.1050

One of the most primary sources of modern Indian history is the official records of the British colonial administration in India. The culture of memos, notings and reports preserved by the British has come to be seen as an authentic source of Indian historiography. Preserved documents from village tahsildar’s office, the collectorate, the commissioner’s office, the provincial secretariats and the lawcourts – are also useful. These added to the records preserved in archives and museums are an important source material for history writing in India.
Apart from the official records, there were diaries of people, accounts of pilgrims and travellers, autobiographies of important personalities, and popular booklets, writings in newspaper and other print media.

We have
( x + a) ( x + b) = x2 + ( a + b)x + ab
Putting a = 2, b = 3 and x = 5 in the indentity:
LHS = ( x + a ) ( x + b )
= ( 5 + 2) (5 +3)
= 7 x 8
= 56
RHS = x2 + ( a + b )x + ab
= (5)2 + (2 + 3) x 5 + (2 x 3)
= 25 + (5) x 5 + 6
= 25 + 25 + 6
= 56
∴ LHS = RHS
∴ The given identity is true for the given values.

Let the duration be x
Let Train A be the train that traveled at 30km/h
And Train B be the train that traveled 35 km/h
Express the distance traveled by train A in term of x
Distance = Speed x Time
Distance = 30x
Express the distance traveled by train B in term of x
Distance = Speed x Time
Distance = 35x
The length of the each train is 200 m.
Therefore, for the train to completely cross each other, Train B (the faster train) will have to be 200 ahead of train A.
Convert 200 m to km
200m = 0.2 km
solve x:
35x - 30x = 0.2 km
5x = 0.2
x = 0.04 h or 2.4 mins
Answer: The train will crossed each other in 2.4 mins.
