Question

Frame and solve the equations for the following statements:
Half of a certain number added to its one third gives $15$. Find the number

Answer 1

Let, the number be $x$

A.T.Q,

$\frac{1}{2}x+\frac{1}{3}x=15$

$⟹\frac{3x+2x}{6}=15$

$⟹5x=15\times 6$

$⟹x=\frac{90}{5}=18$

$\therefore$ the number is $18$
