Answer 1

Step-by-step explanation:

Shivaji Bhonsale I (Marathi pronunciation: [ʃiʋaˑɟiˑ bʱoˑs(ə)leˑ]; c. 1627/February 19, 1630 – April 3, 1680[5]) was an Indian warrior-king and a member of the Bhonsle Maratha clan. Shivaji carved out an enclave from the declining Adilshahi sultanate of Bijapur that formed the genesis of the Maratha Empire. In 1674, he was formally crowned as the Chhatrapati (emperor) of his realm at Raigad.

Over the course of his life, Shivaji engaged in both alliances and hostilities with the Mughal Empire, Sultanate of Golkonda and Sultanate of Bijapur, as well as European colonial powers. Shivaji's military forces expanded the Maratha sphere of influence, capturing and building forts, and forming a Maratha navy. Shivaji established a competent and progressive civil rule with well-structured administrative organisations. He revived ancient Hindu political traditions and court conventions and promoted the usage of Marathi language.

Shivaji's legacy was to vary by observer and time, but nearly two centuries after his death, he began to take on increased importance with the emergence of the Indian independence movement, as many Indian nationalists elevated him as a proto-nationalist and hero of the Hindus.

Answer 2

$\huge \sf { \fcolorbox{yellow}{g}{†Answer†}}$

Required Answer:-

Mean or Average is calculated by dividing the total sum of all items by the total number of items.

In this question, we have to add all the marks and divide it by total number of students.

Class - (1)

No. of students = 100

Mean marks = 30

Then, Total marks = 100 × 30 = 3000

Class - (2)

No. of students = 50

Mean marks = 60

Total marks = 50 × 60 = 3000

Find the mean marks of both classes:

= Total marks / Total no. of students

= 3000 + 3000 / 100 + 50

= 6000 / 150

= 40

\therefore∴ The mean marks of two classes taken together is 40 (Option A).

Note:-

Sometimes average is asked instead of mean. Both are synonymous to each other.

Always add the all total at the last for final answer.
