Hi Nitin,
Let their present ages be a and s respectively.
a:s = 2:3
a/s=2/3
a=(2/3)s ....(1)
now, after 6 years
a+6 / s+6 = 5/7
by cross multiplying
7a + 42 = 5s + 30.....(2)
solving equations 1 and 2
a= 12
s= 36
so the present age of smita is 36 years
Hope it helped you.
Please let me know if any further doubt.
Cheers !!!
