The total mean of 100 observations = 100X50 = 5000 Add correct obs and minus wrong obs from total i.e. 5000-50+150= 5100 new mean= 5100/50= 102

Mean of 100 observation=50 So total sum =50×100=5000 Now one observation is replaced having value 50 by 150 So change in sum=150-50=100 Therefore change in sum=100 So new sum is 5100 Therefore new mean is 5100/100=51

Can a triangle have two obtuse angles? Give reason for your answer.
No, because the sum of three angles of a triangle is 180 degree & sum of any two obtuse angles is always more than 180 degree. So, it can not be possible that a triangle have two obtuse angles.
