Question

a man 50 years old has 8 son born at equal intervals, the sum of the age of the father and sons is 186, what is the age of the eldest son if the youngest is 3 years old

Answer 1

LET THE INTERVAL BE x

1st Son===3
2nd Son===3+x
3rd Son===3+2x
4thson===3+3x
5th son===3+4x
6thson===3+5x
7th son===3+6x
8th son===3+7x
FATHER'S age===50

SUMMING ALL ...................

YOU WILL GET

74+ 28x

BUT ACCORDING TO QUESTION,,

74+28x =186

=> 28x =186-74= 112

=>x=112÷28=3

ELDEST SON .........3+7x

3+7×3=3+21=24

so the age of the eldest son is 24 years




hope it has helped
