b) 161
c) 121
d) 101
e) 137
Read Solution (Total 5)

- ANS C
Let the total score be X
then first highest = 3/11 x
then next highest is 3/11th of the remainder ie 3/11 * (1-3/11)
subtracting the two we get 3/11 - 3/11(1-3/11)
3/11(1-8/11)x = 9
3/11(3/11)x = 9
(9/121)x = 9
x = 121
so x= 121

- (3/11)A-3/11[A-(3/11)A]=9
A=121 - 11 years agoHelpfull: Yes(8) No(1)
- 3/11 x - 3/11 * (8/11) * x =9
3/11* 3/11 * x =9
x=121 - 10 years agoHelpfull: Yes(7) No(1)
- Let total score=x
remaining score= x-x*(3/11)
=(8/11)*x
next highest score=(3/11)*x*(8/11)
now from question
x*(3/11)-x*(8/11)*(3/11)=9
x=121 - 10 years agoHelpfull: Yes(5) No(0)
- 3/11*x=highest score(y)
so,
9=9/121x
x=121 - 9 years agoHelpfull: Yes(0) No(0)
