Answer 2

Answer:

d) None of these

Step-by-step explanation:

Let's take Age of Sachin as x

then, Age of Rahul is x+4

The ratio of their ages is 7:9

that is, x: x+4 = 7:9

Cross multiplying,

7x+28 = 9x

= 28= 9x-7x

= 28= 2x

= 28/2= x

i.e. 14= x

Age of Sachin = 14

Age of Rahul = 14+ 4= 18
