Answer 2

Answer:

seena's present age=28years

beena,'s present age=19years

Step-by-step explanation:

let;

seena's age be x and

beena's age be y

according to the first condition

x=y+9

therefore x-y=9......(1)

according to the second condition

x+10=2y

therefore x-2y=-10

subtracting eq 1 from 2

x - y = 9

X -2y = -10

_________

-y =-19

y = 19

substuting the vale of y in eq 1

x-y=9

x-19=9

x=9+19

x=28
