Answer 2

The age of lisa is 9 years .

Step-by-step explanation:

Let the present ages of sam and lisa be 3x and 4x .

Now, according to the question

=) 3x = (6years + 9 months= 12×6+9=81 months)

=) 3x =81

=) x= 81/3 = 27 months

so , the present age of lisa = 4x = 4×27 = 108 months

= (108/12) years = 9 years

Therefore the present age of lisa is 9 years.
