Question

On her birthday Reema distributed chocolates in an orphanage. The total number of chocolates she distributed is given by $\left(5+\sqrt{11}\right)\left(5-\sqrt{11}\right)$.
(i) Find the number of chocolates distributed by her.
(ii) Write the moral values depicted here by Reema.

Answer 1

(i) As, $\left(5+\sqrt{11}\right)\left(5-\sqrt{11}\right)$

$$\begin{gathered} =5^2-{\left(\sqrt{11}\right)}^2\left[\left(a+b\right)\left(a-b\right)=a^2-b^2\right] \\ =25-11 \\ =14 \end{gathered}$$

Hence, the number of chocolates distributed by Reema is 14.

(ii) The moral values depicted here by Reema is helpfulness and caring.
