Time, Distance and Speed

Today we shall discuss another important topic of Aptitude - Time and Distance. In these type of problems you have to do problems on the speed of Train, Boat etc. Initially these problems may look little confusing, but if you practice well these are very interesting, easy to solve and help you to get good marks. But please keep in mind that the problems of this type are little confusing, people often lose marks because of their lack of concentration. They may feel that they've got the correct answer and choose the answer according to that, but they often endup forgetting CONVERSION (you will know what we've meant by this conversion later). Now before going into details, lets discuss some useful formulas of Time, Distance and Speed.

Shortcut for finding Cubes

Attention Friends... we've came to know that this method is not working for some numbers... So presently we are working on more efficient method than this... We advise you to avoid this method....

In our last posts we've discussed the method of finding Squares (read that post Here). In this post we shall discuss the method of finding cubes. This is very easy and simple method. You just have to put little concentration while learning and should do little practice so that you can do the process in a easy way mentally. And another thing you should keep in mind is, we are posting the step by stem inorder to make you understand the process in detail, but you SHOULD do most of these steps MENTALLY and only should put some important final results on paper. Now lets have a look at the method. In earlier method of finding squares we'd discussed finding the squares with the formula (a+b)², here we shall use the formula (a+b)³. 

Lets start with an example. Assume that you should find out the cube of 18. The general process is multiplying 18 to itself for 2 times (18 x 18 x 18). This process is time consuming and often people end up with the wrong answer caused by confusion and hurry. 

Ok, now lets use our method. here you should use the formula  (a+b)³ = a³ +b³+ 3a²b +3ab². But here you should be little tricky. Have a look.........

Simple Method for Calculating Shortcut for Square - Part 2

We've already seen how to find the squares of numbers which are one more than those whose squares we already know (eg 25, 30, 35 etc).Read that post Here. Similarly, we can find the squares of numbers which are one less than the numbers whose squares are known already to us. For Example,

292 = 30 - 30th odd number = 900 - 59 = 841

392 = 40 - 40th odd number = 1600 - 79 = 1521

342 = 1225 - 69 = 1156

542 = 3025 - 109 = 2916

742 = 5625 - 149 = 5476

942 = 9025 - 189 = 8836

2142 = 46225 - 429 = 45796

Shortcut for Square - A Simple Method

We have already discussed a method for finding the squares of the given number (check that method Here). Now we shall discuss another simplest method to calculate square of the given number. First of all one thing you should keep in mind, for you r convinience we've mentioned each and every step in detail. But You should do all these calculations MENTALLY. I mean without using pen or pencil. So practice well to do these problems orally. Now lets go to the topic, Finding the square of a number ending in 5 is very simple. If the last digit of the number is 5, then the last two digits of the square will be 25.What ever is the earlier part of the number multiply it with one more than itself and that will be the first part of the answer. (The second part of the answer will be 25 only).

Shortcut for Multiplication (Base Number Method Part 2)

We've already discussed about the Shortcut Method (Base Number Method) for doing multiplications. In the earlier post we've discussed doing the multiplication by taking the base as 100 (Click Here to read that). I mean, you can do the multiplication for the numbers nearer to the 100. Then what about the remaining numbers? Well, being the Guide 4 Bank Exams we have solutions for all Banking Problems... So, lets have a look at some more approaches of the Base Number Method so that it will be easier for you to multiply any number with any number :)

Shortcut for Multiplication (Base Number Method)

We've already discussed some short cut tips for Multiplications. You can check that post Here. Now we shall discuss another  Simple and Useful method for Multiplication. In this method we take a base (according to the given numbers) and do the multiplication according to that base. Assume that you have to multiply 97 with 92. The power of 10 to which these two numbers are close is 100. We call this 100 as the base. Now write these two numbers with the difference from the base. 

97 ------>  -3  (because 97 is obtained as 100 - 3)

92 ------> -8 (because 92 is obtained as 100  -8)

Finding the Square of the given Number

In this post we shall discuss about the Shortcut of finding the Square of the Given Number. This is very easy and Simple method. All the you need to learn this method is little concentration and little patience. Remember friends, To make you understand the process clearly, we are posting the process in Step by Step process. But you have to do all these steps Mentally and you should Only write the Answer on Paper... 

Lets start with an example. Assume that you have to find the Square of the number 38.

So, the general process is 38²  multiplying 38 with itself. But this process take much time and effort. So, instead of calculating 38 X 38, just use the formula a² + 2ab + b²

But here you should apply a little trick. If you apply the above formula as it is... you cant get the answer... Just do as mentioned below.

Profit, Loss and Discount - II

<< Contd from HERE

Knowing the labelled price and the discount percentage and the percentage profit of the seller, we can get the actual cost price.


The selling price fixed by the seller includes all other necessary expenses like taxes, carting expenses etc. By giving some discount, the seller gets more customers.

Note  : Commission or brokerage is Added when we purchase, Subtracted when we Sell.

Profit, Loss and Discount

If you buy a mobile for Rs 1000, then it is called Cost Price. If you sell that to me for Rs 2500 (don't worry, I am dumb enough to buy that) then it is called the Selling Price. Here you made a "PROFIT" or "GAIN" of Rs 1500. If i sell the same mobile for Rs. 1800 to anybody else, then I will make a "LOSS" of Rs. 700.

Simply we can say that, if the Selling Price is is more than the Cost Price we can Make Profit. or If the Cost Price is more than the Selling Price then we will end up with Loss.

Profit = Selling Price (S.P) - Cost Price (C.P)
