Question

find the number which should be multiplied to 5 is increased by 80

Answer 1

Answer:

Let us take the number as “x” initially.

Now let us consider that

x * 1 = x

So when we multiply x by 5 times, the product is increased by 80. Hence

x * 5 = x + 80

5x = x + 80

5x - x = 80

4x = 80

x = 20

Therefore the unknown number is 20.

Answer 2

$\huge\boxed{\fcolorbox{red}{ink}{SOLUTION:}}$

• Let x be the number which should be multiplied to 5 is increased by 80

$\huge\fbox\pink{✯By condition✯}$

$⇒5x = x + 80. \\ \\ \\ ⇒5x - x = 80 \\ \\ \\⇒ 4x = 80 \\ \\ \\⇒ x = \frac{80}{4} \\ \\ \\ ⇒ x = 20$
