We are given 4 names. We cannot determine the gender of a person by name only. Prakash lives with his (or her) parents. So, at least 2 people are older than him (or her). Qureshi lives with 3 persons younger to him (or her). We also know Shabdesh lives with his mother & is older than at least 2 people living with him. So, his gender is Male & his mother must be Qureshi. Now, Rajesh lives with his (or her) son & is not older than Shabdesh. So, she must be female & wife of Shabdeesh & mother of Prakash. So, we get in order of age (1 is eldest): Shabdeesh
1. Qureshi (female) – Mother of Shabdeesh
2. Shabdeesh (male) – Son of Qureshi, Husband of Rajesh & Father of Prakash
3. Rajesh (female) – wife of Shabdeesh & mother of Prakash
4. Prakash (male or female) – son or daughter of Shabdesh & Rajesh There are a total of 4 people in the house. Correct option is (a)

Prakash, Qureshi, Rajesh and Shabdesh live together in a house.1. Prak...
Solution:

Given,
- Prakash lives with his (or her) parents.
- Qureshi lives with at least 3 persons younger than him (or her).
- Shabdeesh lives with his mother, and is older than at least 2 persons living with him.
- Rajesh lives with his (or her) son and is not older than Shabdeesh.

Let's try to find out the possible combinations of people living together based on the given conditions.

- Prakash lives with his parents. So, there are 3 people in their group.
- Qureshi lives with at least 3 persons younger than him (or her). So, there are at least 4 people in their group.
- Shabdeesh lives with his mother, and is older than at least 2 persons living with him. So, there are at least 3 people in their group.
- Rajesh lives with his son and is not older than Shabdeesh. So, there are only 2 people in their group.

Now, we need to find out the total number of people in the house.

Since each person belongs to only one group, we can add up the minimum number of people in each group to get the total number of people in the house.

Total number of people in the house = minimum number of people in Prakash's group + minimum number of people in Qureshi's group + minimum number of people in Shabdeesh's group + minimum number of people in Rajesh's group
= 3 + 4 + 3 + 2
= 12

However, this count includes some double-counting of people who may be in more than one group. We need to remove such double-counting to get the correct answer.

On closer inspection, we can see that Shabdeesh is not counted in Qureshi's or Rajesh's group, and Prakash is not counted in any other group. Therefore, the correct answer is:

Total number of people in the house = 1 (Prakash) + 4 (Qureshi and his 3 younger companions) + 3 (Shabdeesh and his mother, but not the 2 people older than him) + 2 (Rajesh and his son, but not older than Shabdeesh) = 10

Hence, the correct answer is option A, i.e., 4.

Answer the following question based on the information given below.Parents have been raising children since the beginning of the human race. But raising children is not the same as parenting. The word itself entered the dictionary only in the 1950s, and did not become a part of the popular vocabulary till the 1970s.Initially, the word was used to refer to what parents did, but over the years, especially today, the word has become completely normative. To parent is a goal-directed verb; it describes a job, a kind of work. The goal is to somehow turn your child into a better or happier or more successful adult, writes Dr Alison Gopnik in TheWall Street Journal.The idea that parenting involves tips, tricks and techniques that enable people to become better fathers and mothers has become widespread, not just in the US, but around the world. The idea is so ubiquitous that the very idea of questioning it seems heretical. But the whole concept of parenting is fundamentally misguided, says Gopnik.For millennia, raising a child did not just involve the parents. There were grandfathers and grandmothers, uncles, aunts, cousins, siblings, friends and neighbours. For most of human history, we lived in these extended family groups. This meant that we learned how to take care of children by practicing with our own little sisters and baby cousins and by watching many other people take care of children, writes Gopnik. But these groups no longer exist in large parts of the world. Theyve been scattered, dislocated, and communicate via the internet. Today, most middle-class parents spend years taking classes and pursuing careers before they have children. Its not surprising, then, that going to school and working are modern parents models for taking care of children: You go to school and work with a goal in mind, and you can be taught to do better at school and work, she writes.Working to achieve a good outcome is a good idea for businessmen or writers, but making a child a product or an outcome does no justice to either the parent or the child, says Gopnik. In fact, there is no evidence to show that the small differences in parenting techniques that many parents obsess over make any difference to the childs adulthood. The most important rewards of being a parent arent your childrens grades and trophies--or even their graduations and weddings. They come from the moment-by- moment physical and psychological joy of being with this particular child, and in that childs moment-by-moment joy in being with you, writes Gopnik.If that means valuing being a parent over parenting, it sounds like a good advice.Q.Which of the following statements, if true, strengthens the argument made in the above passage?A. According to a survey, adults who spent most of their childhood with both parents were happier than those who spent better part of their childhood with one of their parents being away.B. Parents need a strong alpha presentation to inspire a child to trust them and depend upon them.

Four persons, Pavan, Tarun, Venky, and Waqar, are standing on the left bank of a river, whereas another four persons, Qureshi, Ramesh, Sanjay, and Uday, are standing on the right bank of the river. A ferry, which can be used to cross the river and go to the other bank, is present initially on the left bank. The ferry can carry a maximum of two people at a time. However, there must be at least one person in the ferry in order to guide it to the other bank. The travel of the ferry from one bank to the other is called a trip. The eight persons have certain preferences regarding how they would like to travel in the ferry. The following information is known about their preferences:i. If Pavan is present in the ferry, Tarun must also be present in the ferry.ii. If Venky travels to a bank on which Sanjay is already present, Sanjay will immediately travel to the opposite bank.iii. Qureshi will travel in the ferry only when Uday is not present in the ferry.iv. Venky and Waqar cannot travel together in the ferry.Q. After the ferry completed three trips, which of the following pairs of persons cannot be on the left bank?
