Answer:

Let x be the percentage score he got in fifth test,

According to the question,

His score in first, second, third and fourth test are 80%, 84%, 76% and 77% respectively,

Thus, the average of his total score in the five test,

= $\frac{80+84+76+77+x}{5}$

But, Again according to the question,

The average of the five grades as greater than or equal to 80%

That is,

$\frac{80+84+76+77+x}{5}\geq 80$

⇒ $\frac{317+x}{5}\geq 80$

⇒ $317 + x \geq 400$

⇒ $x\geq 83$

Thus, the least score he can get in the fifth test is 83.
