Last month, John rejected 0.5% of the products that he inspected and Jane rejected 0.8 percent of the products that she inspected. If total of 0.75 percent of the products produced last month were rejected, what fraction of the products did Jane inspect?
A/ 1/6
B/ 1/2
C/ 5/8
D/ 5/6
E/ 15/16
Lets be smarter...what if this is the last question and we are left with just 1 minute to do it....
We knw that total rejections were .75% that means Jane would have done the bulk of rejections given that his rejection rate is .80%. clearly the options A,B and C would thus be eliminated that are around 50% mark. Now choose 1 between D and E that would atleast raise your chances of getting the solution right by 50%.
No problems if you have loads of time. This can even work at that time as you have to choose and work between D and E only.
Hope this helps !!
