PERCENTAGE :-
A GIRL GETS 65 MARKS OUT OF 80. WHAT PERCENTAGE OF MARK DOE SHE GET?

Answer 1

Answer:

marks obtained by the girl=81.25=81 Marks

Answer 2

Answer:

81.25 percent

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 80 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=80$100%=80.

Step 4: In the same vein, $x\%=65$x%=65.

Step 5: This gives us a pair of simple equations:

$100\%=80(1)$100%=80(1).

$x\%=65(2)$x%=65(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{80}{65}$100%x%=8065

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{65}{80}$x%100%=6580

$\Rightarrow x=81.25\%$⇒x=81.25%

Therefore, $65$65 is $81.25\%$81.25% of $80$80.
