Answer: (4) None of these
The ratio between the present age of Ravi and Jai = 3:2

Let be the age of Jai is X years.

According to question,

(X + 6 – 4)/(X – 4) = 3/2                                                 (by cross multiplication)

(X + 2)/X – 4 = 3/2

2X + 4 = 3X – 12

X = 16                                          Ans.

Hence, the age of Jai is 16 years.
