question:At 15:00 there were 20 students in the computer lab. At 15:03 and every three minutes after that, 3 students entered the lab. If at 15:10 and every ten minutes after that 9 students left the lab, how many students were in the computer lab at 15:44 ?
Options:
(A) 7
(B) 14
(C) 25
(D) 27
(E) 30
answer:(C)
Stream of consciousness:Initial no of students + 3 * (1 + No of possible 3 minute intervals between 15:03 and 15:44) -
8 *(1 + No of possible 10 minute intervals between 15:10 and 15:44)
20 + 3*14 -8 * 4 = 25

question:Find the third proportional to 4 and 16?
Options:
(A) 80
(B) 12
(C) 64
(D) 78
(E) 72
answer:
(C)
Stream of consciousness:Formula = Third proportional = (b b)/a
A = 4 and B = 16
(16 16)/ 4 = 256/4 = 64
