Question

i thought of a number and multiplied it by 5and added 10 to it . the result is 40 . find the number

Answer 1

$\textbf{Let the number which you thought was K , }$




According to the given information,



( Number is multiplied by 5 ) + 10 = 40


=> ( K × 5 ) + 10 = 40

=> 5K = 40 - 10

=> 5K = 30

$= > K = \frac{30}{5}$

=> K = 6

$\mathbf{Number \: \: which \: \: you \: \: thought \: \: was \: \: \: K \: \: and \: \: the \: \: value \: \: of \: \: K \: \: is \: \: 6} \\ \\ \textbf{ Hence, Number which you thought was 6.}$

Answer 2

Here is your answer⬇️⬇️

Let the number be x.

$\therefore{}$ According to the information,

x × 5 + 10 = 40

5x + 10 = 40

5x = 40 - 10

5x = 30

x = $\frac{30}{5}$

x = 6

$\therefore{}$ $\mathfrak \blue {6 \: is \: the \: number.}$
