Answer 1

Hint: A census is a procedure that involves systematic enumeration, acquiring, and recording of the information that is obtained from the members of the population. Sex ratio can be defined as the number of males to the female in a population.

Complete answer:
The main aim of the census is to count the entire population of a particular locality. During the census, some details of a person are collected that may include- name, age, sex, race, etc. The census helps to provide job opportunities for the unemployed and provides some basic needs to people like a house, water, etc. Census in India is carried every 10 years.
The sex ratio will rise or fall every year. The sex ratio of India in the year 2001 was 933 females per 1000 males. In the year 2011, the number of females to males became 940 to 1000. That means the difference between female numbers in 2001 and 2011 is 7.
The percentage of 933 female to 1000 male in the year 2001 is \[\left( {933 \div 1000} \right) \times 100 = 93.3\]
The percentage of 940 female to 1000 males in the year 2011 is $\left( {940 \div 1000} \right) \times 100 = 94$
The difference in the percentage is $94 - 93.3 = 0.7$

According to the last census 2011, the sex ratio in comparison to the last decade (2002) has gone up by 0.75%. So. the correct answer is option B. It will be gone up by 0.75 percent.

Note:
The first census in India was conducted in the year 1881. The census helps to make new policies and see whether they are implemented in every part of the country.
