Question

vi) Five years hence, the age of Jacob will be three times that of his son. Five years
ago, Jacob's age was seven times that of his son. What are their present ages?​

Answer 1

Answer:

let Jacob present age = X

their son present age = Y

According to question

the age of Jacob will be three times that of his son.=X+5=(Y+5)3

x+5=3y+15

x-3y =10---------eq.1

Five years

ago, Jacob's age was seven times that of his son

x-5=(y-5)7

x-5=7y-35

x-7y = -30----------eq.2

solving the two equation by elimination method

x = 40 & y=10
