Hi,265+x+264+228=4*250==> x+757=1000==>x=1000-757==>x=243which is less than 250
find the deviation they each hae from the mean250+the deviations=x265 is -15 less than 250-15264 is -14 less than 250-14228 is 22 less than 25022add them-15-14+22=-7250-7=243=xit is less than 250answer is Avalue of x=243
