Many people struggle to solve aptitude questions within the limited time they have.
Few methods to overcome this problem is
1) A continous practice
2) Implementing Shortcut methods.
I would like to share few shortcuts which may be useful in almost each and every competetive exams. But with a regular practise. As we know "success cannot be gained overnight"
FINDING THE SQUARES OF NUMBERS WHICH ENDUP WITH '5' (65,35,75,125 etc)
Eg: Find the value of 35 square.
Step 1:
The result of the first digit(left side) will be the product of number's first digit and its successive number. ie 3*4=12
Step 2:
Note: For every square value of a number ending with '5' will be 25. Therefore the value will be 25 which is in the right side.
Therefore final result will be combination of two i.e 1225

- Find square value of 75.
step 1: 7*8=56
step 2: 25(From above note)
Result : 5625
Similarly,
square of 45 = 2025
square of 65= 4225.
