Question:
On her birthday Reema distributed chocolates in an orphanage. The total number of chocolates she distributed is given by $(5+\sqrt{11})(5-\sqrt{11})$.
(i) Find the number of chocolates distributed by her.
(ii) Write the moral values depicted here by Reema.
Solution:
(i) As, $(5+\sqrt{11})(5-\sqrt{11})$
$=5^{2}-(\sqrt{11})^{2} \quad\left[(a+b)(a-b)=a^{2}-b^{2}\right]$
$=25-11$
$=14$
Hence, the number of chocolates distributed by Reema is 14.
(ii) The moral values depicted here by Reema is helpfulness and caring.
