[QUOTE="Ahall, post: 4140781, member: 49426"] This looks like a classic trick question based on order of operation rules. However. I think it’s poorly presented. Pair of earbuds + Pair of earbuds + Pair of earbuds = 30 -> pair of earbuds = 10 Person + Person + Pair of earbuds = 20 -> Person = (20-10)/2= 5 Pair of watches + pair of watches + person = 13 -> pair of watches = (13-5)/2=4 So is a pair of watches 2 watches or watches squared – either way a watch is 2 What about earbuds, is it 2 earbuds or earbuds squared – earbud could be 5 or the square root of 10. I think we have to assume that they want us to do this without a calculator and go with addition of like symbols, even though XX = X^2, not 2X Earbud +person with a pair of earbuds and a watch times a watch = Order of operations Person with earbuds and a watch first – that’s 10, 5 and 2, but do you multiply or add. Based on prior observations, lets add 10+5+2 = 17 Then multiplications Watch time person with earbuds and watch 17* 2 = 34 Add the single ear bud. 34+5 = 39 That’s the answer your supposed to come up with, However, a fair interpretation would also be Earbud = square root of 10 Person = 5 Watch = 2 The middle symbol is a person with a watch and earbuds. With the size changes and placement on the body this could be interpreted a multiplication, rather than addition. (Person, watch, pair of earbuds) = 5*2*10= 100 100* watch = 100*2=200 200+ earbud = 203.162278……… The person also divides the earbuds so that could indicate division (10//5*2=4) The earbuds could also be interpreted as an exponent ((5*2)^10= 10,000,000,000) . Bottom line, a variety of baseless assumptions are needed to solve the “IQ test”, so we learned more about the IQ of the creator than our own intelligence. [/QUOTE]
