This is a separate thread for math , reasoning and english only so that all new and old aspirants can get 150/150 in all the three sections ...........be impeccable ....how to avoid common mistakes , silly mistakes in math , reasoning , and english ....... Join and enjoy cgl 2016 ...
In this thread , post all ur problems and we will try to solve ............ A vocab section will be started by me in this thread word by word and if you will follow this section , I am 100% sure , you will get full marks in one word substitution , synonyms , antonyms , and spell error .
daily 10 words :- Don't search on google ............try to rota daily those words and you will see magic 😃 ............
today's ten words are being posted by me ........... follow and learn :)
In pro paper I attend only 84 is there any chance to qualify
My message to all :-
now we will cover TIME AND WORK topic for three days with each type of questions and short tricks :-
many puys know that there is no short-trick for maths except a good analyse for the question ..................
Lets start with LCM trick in time and work .............don't try to go with percentage trick because it's very complex trick ................
Before going to the topic , everyone must be expert to find LCM within minimum time .
e.g:- A can do a work in 10 days , B in 5 days while C in 20 days .....in how many days , A,B,C together can do the work ?
Solution :- LCM (10,5,20) = 20
so , efficiencies of A,B,C= 2,4,1 ( it means B is more efficient that all others)
so, they will do 2+4+1=7 work in 1 day ..... while total work is 20
so number of days=> 20/7 days .....
this is the basic concept ......remember it and solve any problem within secs ...........
PS:- is baar isi type ka ek question me silly mistake hui thi .....bus poore mains me wahi galat hua 😛 ek tukka galat hua :(
To all who are weak in quant section :-
sabhi log sarvesh kumar verma lelo keval ................... it's good in all aspects aur Pg follow karo ...............
sarvesh kumar verma ka level 1 jo laga lega sahi se , uske concept clear hain ...........................
lekin dhyan rahe ,achi tarah padhna chahe 1 chapter ko 5 din lage ..........
sarvesh kr verma is the key for basic concepts in quant .........

@abhinavrocker bhai can u suggest one book(s) each for quant, english, reasoning and gk. Plz enlist good preparation websites also.
Note: I don't have much issues with basics. I need good books for exhaustive preparation.
P.S. The books should be helpful for both tier 1 & Tier 2.

A can do a work in 15 days and B in 20 days. If they work on it together for 4 days, then the fraction of the work that is left is:-
solution :- (check my previous post for LCM technique)
LCM(15,20)=60
so eff(A,B)=4,3
so, in 4 days => (4+3) work in 1 day .....4*7 work in 4 days=> 28 work done ....
now remaining =60-28 = 32 ...
so fraction = > 32/60 = 8/15
another technique :- (simple hain but hamesha isse gadbad ho sakti hain kyunki fraction ka mamla hain)
4/15+4/20=4+3/15=7/15 ....remaining =15-7/15=8/15
A is thrice as good as workman as B and therefore is able to finish a job in 60 days less than B. Working together, they can do it in:
Solution :- Hamesha efficiency se karne ki koshish karo ..................
A:B=3:1 ...iska matlab no. of days ratio => A:B=1:3 ...
that means A will take one day while B will take 3 days .........
so , 2 days less when B is taking 3 days ...
2*30=60 days less when B is taking 3*30=90 days ...
it mean B will take 90 days and A will take 1/3*90=30 days ...
both will take :- 90 as LCM / ( 90/30 + 90/90) = 90/4 days or 45/2 days .....

A alone can do a piece of work in 6 days and B alone in 8 days. A and B undertook to do it for Rs. 3200. With the help of C, they completed the work in 3 days. How much is to be paid to C?
solution :-
3 days me A aur B in kitna kaam kiya ye dekh lo baaki bacha hua paisa C ke khaate me Cash transfer kardo :p
3/6+3/8= 1/2+3/8=4+3/8=7/8 ....
1/8 *3200 =400 rs .....
dusri technique ..:- LCM of 6,8=24 ....
so , eff=> A,B=> 24/6,24/8=4,3
so , 7*3 =21 work done in 3 days ....
now 3/24 remaining or 1/8 remaining .... which is done by C ...so C will get 1/8*3200=400 rs
