10. In a supermarket average of 4 peoples standing in queue taken 2 yrs before is 55 yrs .Now a person of 45 yrs is added. Find the current age.
Read Solution (Total 2)

- Current Total age=273 & average=54.6 years
Present age of four peoples=(55*4)+(2*4)=220+8=228 years
Present age after fifth person added=228+45=273 & average=273/5=54.6 years - 11 years agoHelpfull: Yes(8) No(0)
- current age avg = 57 yrs
so if 45 added then 57-45 = 12
so 12*4 = 48 and 48/5 = 9.6
the 45+9.6 = 54.6 - 11 years agoHelpfull: Yes(0) No(0)
