How to Solve Logical Reasoning Test 9

Logical Reasoning is to study purely based on the given premises. So no need to add any personal opinion or logic with that of writer's argument.

Let's have an example:

Q.1

A person is carrying an umbrella but there is no cloud in the sky or anything else that leads you to make any conclusion based on your observation. 

Underlying other premises: 

1. He might be going to get his umbrella repaired from any shop. 

2. He might need his umbrella at noon when the sun is high.

3. He might be expecting some rain forecast. 

Thus there is no need to reach to any conclusion promptly without considering all premises.

Summary:

Logical reasoning should solely be based on the given premises, without introducing personal opinions or biases. It's essential to consider all the various possible explanations and not jump to conclusions hastily.

Best Way to Consider:

Without additional information, you should not conclusively determine why the person is carrying an umbrella. This approach ensures that your reasoning is thorough and unbiased, considering all potential explanations within the given premises.

Emphasis on careful consideration and avoid hasty conclusions.

Q.2

Another example of misleading premise: 

When you look at this picture your mind leads to speak '6' but this is not the right answer. 

There is another clue that in this wrong answer, '6' that number doesn't be the right choice or solution. 

Now think about alphabet or some other logical sign. 

Solution:

It's an image of gear in the hand of a driver. Now if you are a keen driver, you can guess that it is an 'R'

Reverse gear. 😊

Q.3 

There are some kids and each of them is playing a game. 

I- The first one claims that she is leading two girls.

II-  The last one claims that there are two girls ahead.
III- The girl in the middle claims that there are two girls ahead of her and two are behind of her.     

If all these statements are true, then how many girls are there in total?

A) Three girls

B) Four girls

C) Three girls

D) Five girls

Explanation: 

If they are playing in a circle, all the statements can be true with just three girls.

- The first girl leads two girls (the other two in the circle).

- The last girl (who is actually the first girl in the circle) has two girls ahead of her.

- The girl in the middle (who is actually the third girl in the circle also) has two girls ahead and behind her (the other two girls in the circle).

The correct answer is indeed A) Three girls.

The statements imply a cyclic structure, where each girl has two girls ahead and behind her, which is only possible in a circular arrangement.

Other Premise:

In a linear sequence, the statements would not be consistent, as we previously discussed. But in a circle, each girl can simultaneously lead two girls, have two girls ahead, and have two girls behind, satisfying all the conditions. 

Q.4 If a boy starts reading a book on the first Sunday of the month and reads 105 pages in a week. What are the total pages of the book if he finishes the book after six months? 

He does not read the book on a Friday.

A) 1000 days

B) 1200 days

C) 2100 days

D) 1500 days

The answer is C) 2100 days

Explanation:

Let's break this down step by step:

1. The boy reads 105 pages in a week.

2. Since he doesn't read on Fridays, he reads for 6 days a week.

3. To find out how many pages he reads per day, divide 105 by 6: 105 ÷ 6 = 17.5 pages per day.

4. Since he reads for 6 months, and there are approximately 4 weeks in a month, he reads for 24 weeks (6 months x 4 weeks/month).

5. Subtract the Fridays from the total days: 24 weeks x 6 days/week = 144 days - 24 Fridays = 120 days.

6. Multiply the total days by the pages read per day: 120 days x 17.5 pages/day = 2100 pages.

7. Therefore, the total pages in the book are 2100.

Note: This calculation assumes that the boy maintains a consistent reading pace throughout the six months.
