let the sum of numbers be x
then x/10=55
x=550
now one number is included let that be Y
now the sum would be 550+Y
and the total numbers would be 10+1=11
550+y/11=60
550+y=660
y= -100
then x/10=55
x=550
now one number is included let that be Y
now the sum would be 550+Y
and the total numbers would be 10+1=11
550+y/11=60
550+y=660
y= -100
