95,89,91, 93 ,x.
Are the five scores , 'x' being unknown and to find.
Hence
(95 + 89 + 91 + 93 + x) / 5 = 93
Add the four known values.
(368 + x) / 5 = 93
Multiply both sides by '5'
368 + x = 465
Subtract '368' from both sides
x = 97
So you must score '97' in your final test to bring your mean/average to '93'.
