A) 1996
B) 1997
C) 1998
D) 1999
Correct Answer: C
Solution :
Ratio of rejection to production of T type of computers in year \[1995=\frac{4}{60}=0.067\] \[1996=\frac{4}{58}=0.069;1997=\frac{3.5}{62}=0.056;\] \[1998=\frac{1.5}{40}=0.038;\,\,1999=\frac{2}{45}=0.044;\] \[2000=\frac{2.5}{50}=0.050\] Hence, the ratio was lowest in 1998.You need to login to perform this action.
