Question

What number increased by 20 percent equals 78?

Answer 1

93.6

78*0.20=15.6
78+15.6=93.6

Answer 2

Answer:

65.

Step-by-step explanation:

Let x represent our required number.

We are asked to find the number which is equal to 78 when increased by 20 percent.

After increasing by 20%, our number would be $x+\frac{20}{100}x=x+0.20x=1.20x$.

To solve for x, we will set an equation as:

$1.20x=78$

$\frac{1.20x}{1.20}=\frac{78}{1.20}$

$x=65$

Therefore, our required number is 65.
