Mean salary = 1450
total employee = 12
∑x/n= x/12 =1450 = 1450*12 = 17400
Now one more person is added whose salary is 1600
so the sum of all salary = 17400 + 1600 = 19000
now new mean = 19000/13 = 1461.53
total employee = 12
∑x/n= x/12 =1450 = 1450*12 = 17400
Now one more person is added whose salary is 1600
so the sum of all salary = 17400 + 1600 = 19000
now new mean = 19000/13 = 1461.53
