look I always prefer short cut rather than detail answers...because I have experience of Gat in which time is too short
total employees ?
let total employees be X
1-avg salary of all employees = 70
2-avg salary of 12 employees= 400 and total of 12 = 4800
3-avg salary of remaining (x-12) employees = 60 and total of these = 60x-720
so mathematically,
(equation 2 +equation 3) / x should be = avg salary of all employees= 70
like
(4800+ 60x -720) / x = 70
solve it
u will get value of x as 408 which is no of all empolyees.
I hope I was able to clear your concept
....but I am dead sure about the answer
