Question

Ian is now twice his sister's age. In 4 years' time Ian will be 16. How old will his sister be then?

Ans : 10

It's not clear from the question,which one we have to find, current age of Ian's sister or in 4 years time? Based on the answer, i can see sister age in 4 years will be 10.

Thanks for your help.

Seriously, you do have all the info you need to work this one out....

Hint - in 4 years' time, he will be 16, so at the moment he is 16 minus those 4 years. The answer to that is twice the current age of his sister.
