25 = 5 × 5
15 = 5 × 3
H.C.F (25,15) = 5
H.C.F (25,15)= 4X+1
4x + 1 = 5
4x = 5 - 1
4x = 4
x = 4/4
x = 1

With age ,Nelson Mandela realized that he had a lot of responsibilities towards his people, his community and his country. As a boy, Mandela did not have a hunger for freedom because he thought that he was born free. He believed that as long as he obeyed his father and abided by the customs of his tribe, he was free in every possible manner. He had certain needs as a teenager and then certain needs as a young man.He slowly understands that it is not just his freedom that is being curtailed, but the freedom of all blacks. It is after attaining this understanding that he develops a hunger for the freedom of his people. Thus , age and experience made his perspective more wide.

The tertiary sector is different from the other two sectors because the other sectors produce goods but this sector does not produce goods by itself. Instead, the tertiary sector activities help in the development of the primary and secondary sectors. These activities are an aid or support for the production process, e.g., transport, communication, storage, banking, insurance, trade activities etc. For this reason this sector is also known as service sector.

let cost(in RS) of one pencil = x
and cost (in RS) of one pen = y
Therefore , according to question
5x+7y = 50 ........ (1)
7x + 5y = 46 .........(2)
Multiply equation 1 by 7 and equation by 5 we get
7(5x+7y)= 7*50
35x +49y = 350 .......(3)
and
5(7x +5y) = 5*46
35x +25y = 230 ....... (4)
Subtract equation 4 from equation 3 , we get
35x + 49y - 35x - 25y = 350 -230
49y -25y = 120
24y = 120
y = 120 /24
y= 5
Substitute y=5 in equation 1 , we get
5x + 7*5 =50
5x+35 =50
5x = 50 - 35
5x =15
x= 15/5
x=3
Hence Cost of One Pencil = x =3
Cost of One Pen =y =5

(i) Organs of the government: Legislature, executive and judiciary are the three organs of the government. Legislature is responsible for making laws, executive organ is responsible for execution or implementation the laws whereas judiciary is there to provide justice to the people or to solve the disputes.
(ii) Power sharing: In India the Union Parliament, i.e., the Lok Sabha and the Rajya Sabha makes laws whereas various ministers and government officials are responsible for the execution of the laws. These ministers are not independent but they are responsible or answerable to the Parliament or State Assemblies. Similarly, although judges are appointed by the executive, they can check the functioning of executive or laws made by the legislatures. This arrangement is called a system of checks and balances.

Let us assume Jacob’s current age is x and his son’s current age is y.
Five years hence, Jacob’s age = x + 5 and his son’s age = y + 5
As per question;
x + 5 = 3(y + 5)
Or, x + 5 = 3y + 15
Or, x = 3y + 15 – 5 = 3y + 10
Five years ago, Jacob’s age = x – 5 and his son’s age = y – 5
As per question;
x – 5 = 7(y – 5)
Or, x – 5 = 7y – 35
Or, x = 7y – 35 + 5 = 7y – 30
Substituting the value of x from first equation in this equation, we get;
3y + 10 = 7y – 30
Or, 3y + 10 + 30 = 7y
Or, 7y – 3y = 40
Or, 4y = 40
Or, y = 10
Substituting the value of y in first equation, we get;
x = 3y + 10
Or, x = 3 x 10 + 10 = 40
Hence, Jacob’s age = 40 years and son’s age = 10 years
