Introduction : Introduction Simple No complex calculations Silly Mistakes Attention to detail Understand question and directions Weightage: 20 questions

What is Data Sufficiency? : What is Data Sufficiency? Is the given data enough to answer a question? No need to find the actual solution Can we find the solution ?

Example-1 : Example-1 What is y? (y-3)(y-2)=0

Example-2 : Example-2 Is point A inside the circle? The radius of the circle is 10 cm Point A is at a distance of 20 cm from point B, which is on the circle.

Example-2 : Example-2 What is price of Kg of Onions today? Yesterday it was 10 Rs/Kg Today it increased by 3 Rs

Typical Problem Structure : Typical Problem Structure One question Two statements Set of directions
