in this question mean is already given and we know that:- mean = sum of total numbers / total number of observations 15 = 2+6+7+a / 4 15*4 = 15+a 60 = 15+a 60-15 = a a= 45 now we have found the value of a=45, we will... read more

in this question mean is already given and we know that:-

mean = sum of total numbers / total number of observations

15 = 2+6+7+a / 4

15*4 = 15+a

60 = 15+a

60-15 = a

a= 45

now we have found the value of a=45, we will put this value in second series:-

mean = sum of all numbers / total number of observations

50 = 6+18+1+45(value of a) + b / 5

50*5 = 70 + b

250 = 70 + b

b = 250 - 70

b = 180
