NCERT Solutions for Class  XI


  1. Write the following sets in the set-builder form:

(i) (3, 6, 9, 12) 

(ii) {2, 4, 8, 16, 32}


 (i) {3, 6, 9, 12}

The given set can be written in the set-builder form as {x: x = 3n, n ∈ N and 1 ≤ n ≤ 4}

(ii) {2, 4, 8, 16, 32}

We know that 2 = 21, 4 = 22, 8 = 23, 16 = 24, and 32 = 25.

Therefore, the given set {2, 4, 8, 16, 32} can be written in the set-builder form as {x: x = 2n, n ∈ N and 1 ≤ n ≤ 5}.

प्रश्न 1. कबीर की दृष्टि में ईश्वर एक है। इसके समर्थन में उन्होंने क्या तर्क दिए हैं?

उत्तर. कबीर ने ईश्वर को एक माना है। उन्होंने इसके समर्थन में निम्नलिखित तर्क दिए हैं

संसार में सब जगह एक पवन व एक ही जल है।

सभी में एक ही ज्योति समाई है।

एक ही मिट्टी से सभी बर्तन बने हैं।

एक ही कुम्हार मिट्टी को सानता है।

सभी प्राणियों में एक ही ईश्वर विद्यमान है, भले ही प्राणी का रूप कोई भी हो।

प्रश्न 2. मानव शरीर का निर्माण किन पंच तत्वों से हुआ है?

उत्तर. मानव शरीर का निर्माण धरती, पानी, वायु, अग्नि व आकाश इन पाँच तत्वों से हुआ है। मृत्यु के बाद में तत्व अलग-अलग हो जाते हैं।

प्रश्न 3. जैसे बाढ़ी काष्ट ही काटै अगिनि न काटै कोई।

सब घटि अंतरि तूंही व्यापक धरै सरूपै सोई॥

इसके आधार पर बताइए कि कबीर की दृष्टि में ईश्वर का क्या स्वरूप है?

उत्तर. कबीरदास ईश्वर के स्वरूप के विषय में अपनी बात उदाहरण से पुष्ट करते हैं। वह कहते हैं कि जिस प्रकार बढ़ई लकड़ी को काट देता है, परंतु उस लकड़ी में समाई हुई अग्नि को नहीं काट पाता, उसी प्रकार मनुष्य के शरीर में ईश्वर व्याप्त है। शरीर नष्ट होने पर आत्मा नष्ट नहीं होती। वह अमर है। आगे वह कहता है कि संसार में अनेक तरह के प्राणी हैं, परंतु सभी के हृदय में ईश्वर समाया हुआ है और वह एक ही है। दूसरे शब्दों में कहा जा सकता है कि ईश्वर एक है। वह सर्वव्यापक तथा अजर-अमर है। वह सभी के हृदयों में आत्मा के रूप में व्याप्त है।


Q 1. What was the focus of the economic policies pursued by the colonial government in India? What were the impacts of these policies?

Ans. The economic policies pursued by the colonial government in India were concerned more with the protection and promotion of the economic interests of their home country rather than with the development of the Indian economy.

Thus, at the time of independence in 1947, India was a poor and underdeveloped country.  Indian agriculture was in a poor condition and mineral resources were not fully utilised. There were only a few industries and many of the cottage and small-scale industries had declined under British rule. Millions of people were unemployed, not because they were unwilling to work but because there were no jobs to be found. The per capita income of Indians was one of the lowest in the world, indicating that the average Indian was extremely poor and could not afford even the basic necessities of life. For instance, the staple food of the average Indian consisted of rice, wheat and millets (like jowar and bajra). Most Indians could not afford to buy a nutritious and balanced diet. A majority of people in India led a miserable life.


  1. Define accounting.

Ans. Accounting is a process of identifying the events of financial nature, recording them in a Journal, classifying in their respective ledgers, summarising them in Profit and Loss Account and Balance Sheet and communicating the results to the users of such information, viz. owner/s, government, creditors, investors etc.

According to the American Institute of Certified Accountants, 1941, “Accounting is an art of recording, classifying and summarising in a significant manner and in terms of money transactions and events that are, in part at least, of a financial character and interpreting the results thereof.”

Q2. Enumerate main objectives of accounting.

Ans.  The main objectives of accounting are given below.

  • To keep a systematic record of all business transactions
  • To determine the profit earned or loss incurred during an accounting period by preparing a profit and loss account
  • To ascertain the financial position of the business at the end of each accounting period by preparing a balance sheet
  • To assist management in decision making, effective control, forecasting, etc.
  • To assess the progress and growth of the business from year to year
  • To detect and prevent frauds and errors
  • To communicate information to various users


Q1. Find the mean deviation about the median for the data 13, 17, 16, 14, 11, 13, 10, 16, 11, 18, 12, 17

Solution: First we have to arrange the given observations into ascending order,

10, 11, 11, 12, 13, 13, 14, 16, 16, 17, 17, 18.

The number of observations is 12


Median = ((12/2)th observation + ((12/2)+ 1)th observation)/2

(12/2)th observation = 6th = 13

(12/2)+ 1)th observation = 6 + 1

= 7th = 14

Median = (13 + 14)/2

= 27/2

= 13.5

So, the absolute values of the respective deviations from the median, i.e., |xi – M| are

3.5, 2.5, 2.5, 1.5, 0.5, 0.5, 0.5, 2.5, 2.5, 3.5, 3.5, 4.5

= (1/12) × 28

= 2.33

So, the mean deviation about the median for the given data is 2.33.

Business studies:

Q1. Why is business considered an economic activity?

Ans.  Business is considered  an economic activity when it is done with the purpose of earning money. The motive of a business is to earn profit primarily. However, there are some other objectives as well like increasing market share, improvement in productivity, employee satisfaction, consumer satisfaction, and social objectives but the primary goal   of business is to make profits. Therefore, it is called an economic activity.

Q2. Explain the concept of business.

Ans. Business is an economic activity involving the production and sale of goods and services undertaken with the motive of earning profit by satisfying human needs.

Q3. Characteristics of Business.

Ans. The main characteristics of business are as follows:

  1. i) an economic activity: All business activities are economic activities and are done with the sole purpose of earning money.
  2. ii) Production and procurement of goods and services: A business activity involves the production or procurement of goods and services. A manufacturer is involved in the production, while a shopkeeper is involved in procurement.

iii)Sale and exchange of goods and services for the satisfaction of human needs:  Any business activity which includes an exchange or transfer of services and goods to earn money. However, goods produced for personal consumption are not included in business activity.

iv)Dealing in goods and services on a regular basis: One time dealing in goods or services cannot be termed as a business activity. The business should happen on a regular basis.

  1. v) Profit earning: Profit earning is the fundamental motive of doing a business. Other motives are there but they depend on the profit motive. No business can last long without making a profit.

vi)Uncertainty of returns: Returns can never be certain in business activity. This happens because of external factors which are outside the control of the business organisation.

 vii) Element of risk: An element of risk is always present in business activity.


  1. What are the goals of scientific enquiry?

Ans. There  is diversity in types of research or studies undertaken by psychologists but they all seem to share some common goals of enquiry, which are as follows-:

Description – This helps to define the phenomena and distinguish it from other phenomenons.

  • The description is necessary because any event or behaviour may have many aspects.
  • For example, the idea of entertainment varies from reading books to going to pubs, depending on the individual.
  • The recording of an event or behaviour is an integral part of the description.

Prediction – Means forecasting of events.

  • It establishes a relationship between two variables.
  • For example, one might say exercising leads to weight loss.
  • In psychology all predictions are made within a certain margin of error i.e. they are not pin-pointed or exact.

Explanation – involves knowing the cause or the reason behind the behaviour.

  • It also tries to understand the conditions under which a particular behaviour occurs. For example, a child behaves rudely whenever he is disturbed so his disturbances become the cause of his rude behaviour.

Control – Means creating change in the phenomenon or behaviour.

  • It refers to making behaviour happen, reduction in it or enhancement in it.
  • The changes produced by psychological treatment in terms of therapy are good examples of control.


  • Psychological research is often conducted to solve various problems faced by file society.
  • Psychology helps in solving problems at the individual, organisational or community level.
  • For example, therapies are provided to individuals and counselling is also there to help them.

At the file organisational level, various psychological concepts like work motivation are used to enhance performance. At the file community level, counselling is provided to help people engage in various, helpful and eco-friendly behaviours.

Computer Science (Python):

Q1. Name any two popular word processing software.

Ans. Two popular words processing software are-

  • OO-writer
  • MS-word

Q2.  What does ‘OS’ stand for?

Ans. OS stands for Operating System.

Q3. Identify the categories into which the software are classified.

Ans. Software is classified into the following two categories:

  • System software
  • Application software
