Brian is twice as old as Charlie. Three years from now, the sum of their ages will be 33. How old are Brian and Charlie today?

Brian is 18 yr old and Charlie is 9 yr old

Step-by-step explanation:

Let age of Brian be B and that of Charlie be C,

Now, B=2*C and also three years after their ages are B+3 and C+3 respectively

(B+3) + (C+3) = 33

Put B=2C

2C+3+C+3=33

3C=27

C=9

Now B=2*9=18

Brian is 18 yr old and Charlie is 9 yr old
