What does test anxiety really look like on the GMAT? For many test takers, it does not look like a panic attack. Instead, it shows up as brain fog, rereading, negative comparisons, mental noise....

the answer could be between 30 and 40 and we need to round off...so even decimal point numbers make difference here....even to guess...
so we need to calcuate so hope it is no good for 2 minutes solving ...that also at the end of the set ....unwise
thanks

I believe there is a mistake in wording the question. It needs to be stated that x represents the weight of each box, and that each subsequent box weights x-x%, and perhaps even give example:
If box weighs 29kg, then the next box will weigh 29kg - 29%. With this, it is easier to comprehend. From the original stem, i concluded that each subsequent box weighs 10% less than the previous one, hence, 10, 9, 8,1, 7.29, and finally 6.561... (if my calculations are correct).
Bottom line, we need to make sure that x changes with the weight of each box, and is not at constant 10%.
