TSA 2012 question 36

Answer is C)

Hi everyone,

I solved this by doing every step but this took so much time, i figure there must be an easier way
Is there another faster way to solve this question?


Ahh I solved that question today doing all the calculations and it took me so long too! Not sure how to do it more efficiently

the only thing i can think of is to do it as 29/290 and not as 29000
then it is a bit faster to calculate every thing , might be some equation we can learn but i don’t think it really is worth our time for the extra 40 seconds
