While Preparing for the SSC JE exam, reasoning is one the scoring topic. It consists somewhat around 25% score in paper I and can add to the SSC JE Pre-cut off. Arithmetic Reasoning is one of the topics and has always been a favourite with the SSC. They ask questions on it in CGL, CHSL and almost all the other examinations it conducts. SSC JE is not an exception. You do get a lot of arithmetic reasoning question every year in SSC JE. SSC JE Arithmetic Reasoning questions are quite easy to solve. It’s all about the basic arithmetic calculations – addition, subtraction, multiplication and division and just a little bit of logic. If you don’t want such questions to take up much of your time in the exam, then we have got some easy SSC JE arithmetic reasoning tips for you that would help you to solve some of the typical questions within a matter of minutes! So, let’s check them out.
SSC JE Arithmetic Reasoning
Let us now take a look at some of the typical questions asked in SSC JE exam related to arithmetic reasoning and how you can solve them correctly and quickly using simple tricks. Let’s get started!
Solving ‘Chess’ Questions
Example 1: In a chess tournament, there are 6 players who would play each other only once. What is the number of matches that would be played in the tournament?
The trick for solving: You don’t have to use complicated probability calculations here. All you need to do is look at the number of players (6 in this case) and then start adding the numbers that follow it in the decreasing order till 1. For example, in this case, you would need to add the numbers like this:
The correct answer is the option (b)-15.
Similarly, if the number of players was 7, we would have added like this: 6+5+4+3+2+1=21.
Solving ‘Group and Group Leader’ Questions
Question: A team of 1200 students and teachers are travelling together. For every 15 students, there is one teacher. So, how many teachers are in the group.
The trick for solving: A lot of candidates would make the mistake of dividing 1200 by 15, to arrive at the number of groups. However, according to the question, a group is not only made by 15 students but it also has a teacher. So, the total number of members in a group is 16. We must divide 1200 by 16, and not 15.
The correct answer would be Option(b)-75
Solving ‘Age’ Questions
Question: A father is now three times as old as his son. 5 years ago, he was four times as old as his son. What is the age of the son now?
The trick for solving: The best way to do is by option elimination. You can do it by formula, but that would take a fair amount of time. On top of that, the chances of getting it wrong are high as well. Therefore, the best way is to eliminate the wrong answers.
So, what is the first option that you should take? You should always start with the largest number and not the first option. The largest number here is 20.
If son’s age is 20 now, fathers age is 60
5 years ago, the son was 15 years of age and the father was 55. As clearly seen, this is wrong.
Next, you should not take the number that immediately follows the largest number,i.e. 18. You should take the number that follows 18, i.e. 15.
If son’s age is 15 now, fathers age is 45.
5 years ago, the son was 10 and the father was 40. This is the right answer.
Therefore, the right answer is the Option (c)-15.
Quick SSC JE Arithmetic Reasoning Tips
- Try to eliminate the wrong answers first, instead of creating a formula for coming up with the right answer straight away. This would help you save time.
- Consider the largest number in the options first. If that doesn’t work, take the third largest number next.
- Never hesitate to do rough work. It makes your answers accurate.
Question 1: A father said to his son, “I was as old as you are at the present at the time of your birth”. If the father’s age is 38 years now, the son’s age five years back was:
A. 14 years
B. 19 years
C. 33 years
D. 38 years
Question 2: In a football tournament, there are 10 teams. Each team would play each other exactly once. How many matches should be played?
Answer – B
Question 3: A group of 55 army men are travelling together. For every 10 soldiers, there is one Captain. How many captains are there in the group?
Answer – C
