a+b+c+d+0.35 / 5 = 0.5
a+b+c+d+0.35 = 2.5
a+b+c+d = 2.15
Now assuming the next greatest value to 0.35 would be 0.36. And assuming that b=c=d which is 0.36 then
a+ 0.36 +0.36 + 0.36 = 2.15
a= 2.15- 0.36*3
a= 1.07
Now making another assumption that b=c=d=0.35 then also
a + 0.35*4 =2.5
a = 1.1
and hence the greatest value of amongst the 5 cannot be greater than 1.1. D
D should be the answer as per me.
(I could be wrong guys!!!!!!!!)
