A man is 3 years older than his wife and four times as old as his son. If the son becomes 15 years old after 3 years. Then what is the present age of the wife?
-
60 years
-
51 years
-
48 years

45 years
Let the age of son = x
Age of man = 4x
Age of wife = 4x - 3
Now,
x + 3 = 15
x = 12 years
Age of wife = 4 x 12 - 3 = 48 - 3 = 45 years

Number of ticket of Ann = 2x,
Bill = 3x
Ken = 4x
Ratio of ticket after a game Ann = 5x, Bill = 2x, Ken = 2x
Ticket won by Ann = 5x - 2x = 3x
Ticket lose by Bill = 2x - 3x = -1x
Ticket lose by Ken = 2x - 4x = -2x
Number of tickets won by Ann = 21 which is 7 times the ratio i.e. 3 x 7 = 21
Similarly, Number of tickets lose by Ken = - 2 x 7 = 14 Ticket.
