21-8=13; 13*2=26
27-9=18; 18*2=36
24-6=18; 18*2=36
Hope this is right!

Yes. Left number minus right number then double your answer.

I would go with red's method as in our county (lincs), these questions have to be completed in 2 stages

Dear Senthi
Although your method works it is not an efficient way of working out the answer. Reds version is less time consuming.
Dear Stocky
These types of questions when set by GL Assessment as the test provider, can be 1, 2 or 3 operations/stages.

ooh cheers Patricia, I've been misadvised along the way, as was definitely told 2 stages. Whilst my DD has just passed, my DS sits in Sep 12 so that will help with our prep. Thanks again
