Answer:
5/6
Step-by-step explanation:
3/4 is less than 5/6 by ...
5/6 -3/4 = 10/12 -9/12 = 1/12
The number that is greater than 3/4 by 1/2 is ...
3/4 +1/12 = 9/12 +1/12 = 10/12 = 5/6
5/6 is greater than 3/4 by the same amount that 3/4 is less than 5/6.

This is a trick question -- checking to see if you're awake.
If A < B by some amount, then B > A by that same amount.
If B -A = q, then A +q = B.
Mean of data = sum of values ÷ number of data
We have three values; 84, 87, and
Sum of values =
=
We want the value of
to give mean between 85 and 90 inclusive
Hence, the value of
is between 84 and 99 inclusive
