Answer 1

Answer:

Required Answer:-

Let the number=x

• According to question

$x×212÷115-718=156$

$\longrightarrow$${\dfrac {212x}{115}}-718=156$

$\longrightarrow$${\dfrac {212x}{115}}=156+718$

$\longrightarrow$${\dfrac {212x}{115}}=874$

$\longrightarrow$$212x=874×115$

$\longrightarrow$$212x=100510$

$\longrightarrow$$x={\dfrac {100510}{212}}$

$\longrightarrow$${\underline{\boxed{\bf {x=474.5}}}}$

$\longrightarrow$$\sf {Approximately=474}$

$\therefore$$\sf {The\:number\:is=474.}$
