Given : Maria is one less than twice the age of Ana.  

after four years Maria will be 18 less than thrice Ana’s age.

To Find :  present ages

Solution:

Maria is one less than twice the age of Ana

Ana Age = A

Maria Age = 2A - 1

after four years Ana Age = A + 4

after four years Maria Age = 2A -1 + 4 = 2A + 3

Maria will be 18 less than thrice Ana’s age.

=> 2A + 3  = 3(A + 4) - 18

=> 2A + 3 = 3A + 12 - 18

=> 9 = A

Ana Age = 9

Maria Age = 2(9) - 1   = 17
