Hi guys!
Really simple statistics percentage problem, but I'm having one of those brainfart moments:
So the original question states:
A increases by 2 million while B decreases by 2 million.
However, new information suggests the rise A was under-estimated by 11%, and the fall in B was overestimated by 26%, what is the net increase between the two?
My math suggests the answer should be a net increase of 740 000 (2 000 000*1.11 = 2 220 000; 2 000 000*0.74 = 1 480 000; 2 220 000 - 1 480 000 = 740 000).
Can someone reassure me I am right or suggest why I am wrong. I am getting confused as to whether I should multiple by 1 + % for underestimates and multiple by 0 - % for underestimates.
