In a factory, each day the expected number of accidents is related to the number of overtime hour by linear equation. Suppose that on one day there were 1000 overtime hours logged and 8 accidents reported and on another day there were 400 overtime hours logged and 5 accidents. What is the expected number of accidents when no overtime hours are logged?  Pick.
A) 2
B) 3
C) 4
D) 5
E) 6
Explanation :   Let, the number of over time hours be x and expected number of accidents be y.   We will use the equation y = mx + c , where m and c are constant.   Now,according to the question,   if x =1000, then y=8   i.e 8=1000x + c ----(i)   And, if x=400, then y=5   i.e 5=400x + c. ----(ii)   On solving these equations, we get   m=1/200 and c=3.   Hence, in case, no overtime is there i.e x=0, then the number of expected accident will be 3.   Answer : 3
