Focus more on Quant and DI preparations

Around 1/4 of the CET paper is covered with Quant and Di i.e around 45-50 marks. You must solve this problems with perfect accuracy.

**1. Permutation / Combination / Probability:**

You have to mug up events, arrangements and concepts of selection.

Always clear difference between probabilty is no of ways and permutation is arrangements.

In probablity : in how many ways the event occurs.

eg: spining a coin has 2 possible outcomes Head H or Tail T .

Possiblity of head is 1/2

In Permutation/Computation : in how many ways the event is arranged .

eg 3 letters ABC n=3 …. so formula is n! i.e 6

ABC,ACB,BAC, BCA,CAB,CBA

**2. BODMAS and approximation questions:**

You must mug up all the square roots upto 30 and cube root upto 20.

Learn tables upto 30 to speedite the calculations.

You must know the fractions i.e 1/4th of the number and percentages.

The approximations based questions can be solved verbally instead using paper and pencil .

7 + (6 × 52 + 3) such questions has to be solved verbally

like 343 is cube of 7

**3. Time /Speed / Work/ Distance.**

Questions are simple and generally in relative speeds, races, number of days and time taken to conplete the work. You need to be very fast in such questions .

**4. Clocks and calendars :**

You must know some concepts that the clock always has 360 degrees. So 1 minute makes 360/60 i.e 6 degrees.

About Calenders you must know the leap year calculations and general rule about days recognition like “divisibility by 7”.

eg : today is 3 jan 2012 which is tuesday so what day will be on 26 jan 2012 so the difference between 26 and 3 is 23 so divide it by 7 so the remainder is 2 so add 2 in 3 so its thurday.

**5. Venn – Diagrams **

Formulas like n(AuB) and n(AuBuc) is sufficient to solve the problems.

**6. Datainterpretation**

You must make your calculation part very strong . Use approximate values where there is a big difference in numbers . Make your percentage logic strong as there are number of questions based on percentages.

There are problems like percentage increase ? always use formula like

(200 – 100 / 100) * 100 to calculate percentage increase.

There are basically bar, line and pie charts come in exams and mostly given

productions / earnings / output verses years.
