Answer 2

$\large{\underline{\red{\rm{AnswEr:}}}}$

$\bold\green{\underline{\underline{Let:}}}$

The number be X

$\bold\green{\underline{\underline{Given:}}}$

A number when increased by 23% becomes 861

$\bold\green{\underline{A.T.Q}}$

⟹X+X*23%=861

⟹X+X*23/100=861

⟹X+23X/100=861

⟹100X+23X/100=861

⟹123X/100=861

⟹123X=861*100

⟹X=861*100/123

⟹X=7*100

⟹X=700

Hence,

$\bold\orange{\boxed{The\: number=700}}$
