ans is 69...
current age of 6 is 6*41= 246

45*7-(43-2)*6=69 (Ans)

6 person present avg; 41, after 7th person join became 45.
difference 4
hence (6*4)+45=69

Total age of 6 persons is x,after two years total age of 6 persons is x+12
Average age of 6 persons is after two years is 43
So (x+12)/6=43,then solve x,
After 7th person is added then (x+7th person age)/7=45
So we will get 7th person age easily i.e. 69

x+2(6)/6=43 => x=258
now 246+y/7=45 => y=69
ag of that person is 69

a+b+C+d+e+F+12=(43*6)=258
a+b+c+d+e+f=246
a+b+c+d+e+f+g=(45*7)=315
315-258=69
6 years agoHelpfull: Yes(1) No(0)
ans is 57
because 6*43=258
and a person has joined
so,
7*45=315
age=315-258=57
5 years agoHelpfull: Yes(1) No(1)
after 2 year avg will be 43
so present avg =43-2=41
now let E6 is sum of all 6 person's age
ie E6=41*6=246
let 7th person's age is x
according to question (E6+x)/7=45
x=(45*7)-(246)
on solving x=69 ie ans

let's assume A,B,C,D,E,F are the current ages of all 6 persons and since after two year average of ages will be : (A+B+C+D+E+F+2*6)/6 = 43(given) .........................eq(1)
and if seventh person get added then current average of ages will be : (A+B+C+D+E+F+G)/7 = 45 (given) ;G is age of seventh person.
put the value of eq(1) in above equation.....
(G+246)/7 = 45
G = 69 Ans.
