A) 84 sec
B) 72 sec
C) 66 sec
D) 60 sec
Correct Answer: A
Solution :
\[\frac{365-361}{2}\]\[=K\left[ \frac{365+361}{2}-293 \right]\]= 70 KÞ \[K=\frac{1}{35}\] Again \[\frac{344-342}{t}=\frac{1}{35}\left[ \frac{344-342}{2}-293 \right]=\frac{10}{7}\] Þ \[t=\frac{14}{10}\]min = \[\frac{14}{10}\times 60=84\]sec.You need to login to perform this action.
