"A)2",
"B)4",

"D)8"
] | C | 302 x 304 x 306 x 308 => unit digit 4
312 x 314 x 316 x 318 => unit digit 4
392 x 394 x 396 x 398 => unit digit 4
So we have 10 numbers ending by 4 to multiply.
Given that 4 x 4 = 16, we have 5 numbers ending by 6 to multiply
Given that 6 x 6 = 36, we have 3 numbers ending by 6 to multiply
So the unit digit is 6

aquarat_16603 | aquarat | All of the students of Music High School are in the band, the orchestra, or both. 80 percent of the students are in only one group. There are 136 students in the band. If 60 percent of the students are in the band only, how many students are in the orchestra only? | [
"A)33",
"B)39",
"C)34",
"D)42"
] | C | % of students in one group only = 80%
% of students in both groups = 100 - 80 = 20%
% of students in the band only = 60%
Number of students who are in band = 136
20% + 60% = 80% = 136 Students
Finding total students:
x = (136 x 100)/80
x = 170
Students in orchestra only = 170 - 136 = 34
