Question:

If the$\dfrac{2}{7}$ th part of a certain sum was donated

and$\dfrac{1}{4}$ th was spent on education, then the balance amount will be

Answer:

Let total amount = x

Part of amount donated = $\dfrac{2x}{7}$

Part of amount spent for education = $\dfrac{x}{4}$

Balanced amount = x - $\dfrac{2x}{7}$-$\dfrac{x}{4}$

= $\dfrac{28x - 8x - 7x}{28}$

= $\dfrac{13x}{28}$

2x

-\dfrac{x}{4}

4

x

= \dfrac{28x - 8x - 7x}{28}

28

28x−8x−7x

= \dfrac{13x}{28}
