The mean of a certain number of observations is 32. Find the resulting mean, if each observation is,
1. Increased by 60%
2. Decreased by 20%

mean of the data=32
1. if every observation is increased by 60% then mean also increases by 60%
mean=32*60/100+32 =19.2+32=51.2
2.if every observation is decreased by 20% then
mean also decreases by 20%
mean=32*20/100+32=6.4+32.4=38.4
