Ssc aspirants Prakasheen4u welcome you all..


 
First of all I am going to tell you that Ssc exam contains 4 sections-

1.Reasoning

2.Maths

3.English

4.General Awareness

Here I am going to discuss few topics that is common and very important for the exam point of view-

Simplication tricks to make calculation fast-

Memorise table from 1 to 30.

Squares upto 50,

Cubes from 1 to 25,

Break addition into parts to make calculation  easier and error free ex. 45+67=(40+60)+(7+5), for fraction addition ex. 1 1/2+3 1/2=(1+3) +(1/2+ 1/2)

Multiplication also do it part wise.

Percentage effective use at diff places-
1/2=50%, 1/3=33.33%, 1/4=25%, 1/5=20%, 1/6=16.66%, 1/7=14.7%, 1/8=12.5%, 1/9=11.11%, 1/10=10%, 1/11=9.09%, 1/12=,  2/5=40%, 3/4=75%.

Use % thoughts effectively ex. 10% of 25 = 25% of 10,   355% of 500= 500% of 355, suppose 2/5 of 100= twice the 5th part of 100.
