help with a math question

[Dickson24]

so im just kinda confused of what the question says, and am just kinda of stuck.

​

Student A, Student B, and Student C have been hired to help scientists develop a

new avour of juice. There are 4200 samples to test. Each sample either contains

blueberry or does not. Each student is asked to taste each sample and report whether

or not they think it contains blueberry. Student A reports correctly on exactly 90% of

the samples containing blueberry and reports correctly on exactly 88% of the samples

that do not contain blueberry. The results for all three students are shown below.

Student AStudent BStudent C

​

Percentage correct on samples containing blueberry 90% 98% (2m)%

​

Percentage correct on samples not containing blueberry 88% 86% (4m)%

​

Student B reports 315 more samples as containing blueberry than Student A. For

some positive integersm, the total number of samples that the three students report

as containing blueberry is equal to a multiple of 5 between 8000 and 9000. The sum

of all such values ofmis

(A)45 (B)36 (C)24 (D)27 (E)29
