prats92 Saysscrapped .....
It is coming out to be 10200..Avg. salary = 600.
So, 120 people have excess of 3400 salary.
This is to be nullified by rest of the employees.. say their count is 'x'.
So, x*(-40) + 120*3400 = 0
=> x = 120*3400/40 = 10200
ACE bhai doubt !!!
let total number br X
600X = 4,80,000 + 560X - 67200
X=10320
whats wrong??

It is coming out to be (10200+120)..Avg. salary = 600.
So, 120 people have excess of 3400 salary.
This is to be nullified by rest of the employees.. say their count is 'x'.
So, x*(-40) + 120*3400 = 0
=> x = 120*3400/40 = 10200
No where near options.. Please check question..
Nothig is wrong Jain bhai..
In my solution, x is number of workes.. While in your solution, X is number of total employees..
So, if you add 120 to 10200, you will get 10320..
I did not complete solution there as options are no where near to it..
So, either options are mistyped or some information is missing.. Anyway.. I edited and added a note there..
prakash_miku Sayswhat is the answer given..they may have missed a 0 in each option..(b)10320 and if thts correct then i'll tell ya the approach :D. i think it says average salary of the rest of the employees is 560.
