Explanation:

Let a, b, c, and d is the marks of Amit, Ram, Rohit and Kirti respectively.
Clearly, we have :
a+b+c+d=450….(i)
c=2(b+d) ….(ii)
a=c….(iii)
from i & ii
a+c+c/2 =450; (we have a=c)
c+c+c/2= 450
5/2c=450
c=180;
a=180
b+d= c/2= 180/2=90
a, c is more than 95, b, d is not more than 90.
Therefore, Amit and Rohit will go to next level examination.
