Has anybody tried TIME's Trishna ?
Ya TRISHNA is also a good book for quants as u can have a very detailed knowledge of quants basic concepts..but for advanced level Arun sharma is good for CAT

Hi Neha,
Thanks for uploading such agood stuff; many shortut techniques and questions for practice.
While going through the details I stuck on your shortcut techniques (below) specified for “Compound Interest and Simple Interest”.
"??:
Here’s a table for calculating SI and CI
------------------ S.I. ------------- C.I.
1--------------------S -------------Upto S
2------------------2S--------------- Upto 2S+X
3------------- -----3S--------------- Upto 3S+3X+
4--------------------4S ------------ Upto 4S=6X++
5--------------------5S ------------ Upto 5S+10X+++
6-------------------6S ------------ Upto 6S+15X+++
“++” it roughly takes a value of Rs. 2 for Rs 100 of X.
Q. the difference between CI and SI is Rs 9848 at 8% interest put out for 4 yrs. What ids the principle?
Method-
For 4 yrs. The value that corresponds is 6X++
So 6X++ = 9848
Here we divide the amt. by 100 and ignore the decimal part so we get 98 and now we subtract 2 from it and now we get 96
So 6x =96 , x =16
8% of SI= 16
So 1% of SI = Rs. 2.
100% of SI =200
200 is 8 % of principle therefore the principle is 2500.
Query1: Why devide it by 100,
Query2: when “++” it roughly takes a value of Rs. 2 for Rs 100 of X. " what does +++ &+ means for no 3, 5 & 6 in the technique.
Help
