Answer Posted / t eswara rao
THE ANSWER IS : FRANK WILL BE AT AN AGE OF 14YR. IN FOUR YEARS
SOL:
AS PER CONDITION-1: F = J-15
AS PER CONDITION-2: J+5 = (F+5)X2
SO THE EQUATION WILL BE AS FOLLOWS
J+5 = (J-15+5)X2
J = 2J-25
J = 25
SO SUBSTITUTE THE VALUE IN CONDITION-1 AND THE VALUE OF F
F = 10
AFTER 4 YRS
F = 10+4
= 14
