AVERAGE between 90 and 100%
means not including 90 and 100% but not including 90 or 100%


average=(sum of values in set)/(how many values in the set)

so
4 exams, so there are 4 values
average=(sum)/4

the sum is the known+unknwon
sum=76+99+86+x

so
90<span><</span>average and average <span><</span>100
or
90<span><</span>average<span><</span>100


lets say average=a

a=sum/number
a=(76+99+86+x)/4

90<(76+99+86+x)/4<100
90<(76+99+86+x)/4 and (76+99+86+x)/4<100

solve each for x and find intersection

90<span><</span>(76+99+86+x)/4
times 4 both sides
360<span><</span>261+x
minus 261 both sides
99<span><</span>x


(76+99+86+x)/4<u><</u>100
times 4 both sides
261+x<u><</u>400
minus 261 both sides
x<u><</u>139


so

99<u><</u>x<u><</u>139
since max score is 100
99<u><</u>x<u><</u>100

interval notaion is
[99,100]


answer is 2nd one
