let

x---------> Aviva’s age

y--------->Kanti’s age

z--------> Lakshmi’s age


we know that


y=x-3-----> equation 1

z=2*y-----> equation 2

substitute equation 1 in equation 2

z=2*(x-3)

so

Aviva’s age------> x

Kanti’s age-------> x-3

Lakshmi’s age----> 2*(x-3)


therefore


the answer is the option

b) 2(x-3)
