five years ago average age of A,B,C,D is =25
at presesent their average age = 25+5 =30 yrs
sum of these four peoples age = 30*4=120----(1)
if P is included their average age=29
sum of these five people age= 29*5=145---(2)
therefore Prem age = (2) - (1)
= 145-120
=25years

average age of A,B,C,D = 25
Pesen average age = 25+5 = 30
sum of four friends = 30 × 4 = 120. .........(1)
including P = 29
sum of five friends = 29 × 5 = 145 .........(2)
age of P = (2) - (1)
= 145 - 120
= 25
Pesen average age = 25+5 = 30
sum of four friends = 30 × 4 = 120. .........(1)
including P = 29
sum of five friends = 29 × 5 = 145 .........(2)
age of P = (2) - (1)
= 145 - 120
