Q:
A) 30 | B) 40 |
C) 60 | D) None of these |
Answer: D) None of these
Explanation:
Explanation:
Let t be the time after Kajol starts, when she meets Ajay, then
t = 300/(x+y)
This should be less than 2.5 or (x+y)>120
Since y= 3x/2 => y > 72
This (y>72) is greater than 67.5 km/h and hence Shahrukh will always overtake Ajay before he meets Kajol.
