Question

What percent of 800 is 78?

Answer 1

$\underline\bold {\huge {ANSWER\::}}$

9.45%

Steps:-

We make the assumption that 78 is 100% since it is our output value.

Let the required percentage be x%.

According to the question,

This gives us a pair of simple equations:

⇒ x% of 800=78.

⇒ x × 800/100 = 78.

⇒ x × 8 = 78.

⇒ x = 78/8

⇒ x = 9.75%.

Thus , 9.75% of 800 is 78.

Answer 2

Answer :

9.75 %

Step By Step Explanation :

Let the required percent be k %.

Now,

    k % of 800 = 78

⇒ k/100 × 800 = 78

⇒ k × 8 = 78

⇒ 8k = 78

⇒ k = 78/8

∴ k = 9.75 %

Hence, 9.75 % of 800 is equal to 78.
