**Perfect Cube Series**

Perfect cube series is a arrangement of numbers in a certain order,where some numbers **this Types of Series are based on cube of a number which is in same order and one cube number is missing in that given series.**

we need to observe and find the accurate number to the series of numbers. This type of problem are given in Quantitative Aptitude which is a very essential paper in banking exam.Under below given some more example for your better practice.

All numbers are arranged in sequence order. we need to observe and find the accurate number to this type series of numbers. Here we learn the perfect cube series of Example.

This type of problem are given in Quantitative Aptitude which is a very essential in banking exam. Under below given some more example for your better practice.

In perfect cube series number is a combination of cube number are arranged. In example 1) 1331, 1728, 2197, ? where you need to count them in a one step or two step calculation for obtain the difference common result according with the series of ratio numbers .

At first you can calculate missing number in ratio series and that you place the actual missing number in the ? or missing place. Be prepared when you calculate differences because it is either one or two step calculation. So when you calculate and get result of two difference numbers you need follow some step wise.

At first calculate the first number cube value and second number cube value if all number are maintain a sequential order cube value then follow same steps which is carry up to last and after that you get actual missing number by finding the common value when you put the missing number you have noticed that all series numbers are common difference in between them.

This kind of missing series calculation you go thorough some common calculation shortcut tricks using cube and cube shortcut tricks, or you memorize the 1 to 30 cube series number value.

In this type series example questions, it is sounds hard, but it really isn’t. Get it? Once you have done this, by practice with more example then you just easily can do in your way as well competitive and as in bank exam also . So, each of our examples are given below.

hi admin, can u give me detailed description in this cube number series, as it is not much clear to me

very nice

But sir Jaime kisi particular disit ka cube puche to jaise 21ka kya hoga uska kaise nikale

6 question is wrong given here

TRICK: For Cubes:

Look last digit, if it is (0, 1, 4, 5, 6, 9) then it is cube of a number ending with same otherwise if cube ends with (2, 3, 7, 8) then it is cube of a number ending with (8, 7, 3, 2) i.e. [10 – last digit] respectively.
