Checking Divisibility of a Number - Aptitude Skills Program Training in SLA Chennai

You can check if a number is divisible by 2, 3, 4, 5 and so on till 13. There are some simple rules to check divisibility. Let us look at some examples for divisibility by 3 and 4.

Divisibility by 3

-------------------

A number is divisible by 3 if and only if the sum of the digits is divisible by 3.

Example:

Which of the following two numbers is/are fully divisible by 3: 97533222 or 97533322?

Answer: 97533222

Reason:

Sum of digits for 97533222 = 33 / 3 = 11

Sum of digits for 97533322 = 34 / 3 = 11.33

Divisibility by 4

--------------------

A number is divisible by 4 if and only if the last 2 digits is a number divisible by 4.

Example:

Which of the following two number is fully divisible by 4: 5555444446 or 5555444448 ?

Answer: 5555444448

Reason:

Last 2 digits for 5555444446 are 46, 46 is not fully divisible by 4 (46/4 = 11.5)

Last 2 digits for 5555444448 are 48, 48 is fully divisible by 4 (48/4 = 12)

How to Deal with Many Zeroes in a Numerical Aptitude Test

One of the common ways people make mistakes while doing basic math in numerical reasoning / quantitative aptitude/ problem solving tests is because of the confusion with zeros (0's). The moment someone has to deal with something like this:

34000*60000*1000000

or

50 thousand people earning 1.3 million $ each for 200 days = ?

You find it difficult or you are overwhelmed. You miss zeros, add extra zeros, get all zero'd up - so how do you do it without getting confused like crazy?

Here's a valuable tip - use '10 to the power notation'. If you don't know what it is, then spend a little time learning it - the notation is essentially

100 = 10-squared = 10^2 (10 to the power of 2)
1000 = 10^3
10000 = 10^4
million = 10^6
billion = 10^9

so

50 thousand people earning 1.3 million $ each for 200 days = ?

will be represented as follows:

(5*10^4)*(1.3*10^6)*(2 * 10^2)

= 5*1.3*2* (10^4*10^6*10^2)
= 6.5*2*(10^(4+6+2))
= 6.5*2*(10^12)
=  13*10^12  

So, that is the magic for solving maths problems with too many zeros. You want to know many such tips and tricks while you are doing  a technical course.
