90.5 percent
average = 89% average = (94% + 84%)/2 = 89%
average of 71%, 84% and 90% = 81.67% = (71% + 84% + 90%)/3 = 245%/3 = 81.67%
96+84=180 average=180/2 average=90% same as normal averaging

Simi's tests so far can be expressed as 320 percent divided by four. To average 84 percent, she would need five times 84 or 420 percent. The difference is 100%. Assuming all the tests are equally weighted, she needs 100% on the 5th test.
