The average salary per head of all the employees of an institution is $60. The average salary per head of 12 officers is $400 and average salary per head of the rest is $56. Find the total number of employees in the institution.
a)1000
b)900
c)1030
d)1032
e)950

• no.of employees=x
  thrfr total sum=60x
  avg of 12 employee=400
  =>sum=400*12=4800
  avg of rest of the employee(x-12)=56
  =>sum=56*(x-12)=56x-672
  total sum,60x=4800+56x-672=56x+4128
  solving we get x=1032
