Addition Shortcuts (Mental Maths)
- 342 + 557 + 629 + 746 + 825 = ?
- When we are adding three-digit numbers, first add-two-digits at a time (Units and Tens Place).
- 42 + 57 + 29 +| 46 + 25 = 199
- To add 42 and 57, mentally treat 57 as 50 + 7 ( Because 50 would facilitate quick addition)
- So, 42 + 57 = (42 + 50) + 7 = 92 + 7 = 99
- Similarly, 99 + 29 = (99 + 20_ + 9 = 128
- 128 + 46 = (128 + 40) + 6 = 174
- 174 + 25 = (174 + 20) + 5 = 199
- The last two digits (the units place and the tens place)

In this post, we shall discuss about the basics Data Interpretation. The Data Interpretation is also called as comprehension of mathematics. Because, in reading comprehension, we have to study the passage and answer the questions followed by that passage. In the same way, in Data Interpretation, some data is given in the form of graphs, charts and tables followed by questions. We have to study, understand and analyze the data to solve the questions. Here we have to keep in mind that, even a 10th standard boy can solve these problems. But you've to solve these problems IN TIME.
So you have to practice well so that you can do the small calculations (like additions, subtractions, and simple multiplications) with a glance (see here for shortcuts in mental maths). Now lets have a look at some basic details of Data Interpretations.

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....
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.........

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

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.

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.
