Question

The sum of a number and two third of it is 20. Find the number​

Answer 1

Let the number be x.

Two-third of the number = 2x/3

ATP,

x + 2x/3 = 20

5x/3 = 20

5x = 60

x = 60/5

x = 12

The number is 12.

Answer 2

Answer :

12

Explanation :

If we assume the number as $\rm x$

We can say that,

Sum of $\rm x$ and ⅔ of $\rm x$ is 20

According to the question,

$\rm \implies \:x + { \dfrac{2x}{3} } = 20$

$\rm \implies \: \frac{3x + 2x}{3} = 20$

$\rm \implies \: 3x + 2x = 20 \times 3$

$\rm \implies \: 5x = 60$

$\rm \implies \: x = \frac{60}{5}$

$\rm \implies \: x = 12$

${ \underline {\sf{ \therefore{The \: number \: is \: 12}}}}$
