A) \[\frac{2}{7}\]
B) \[\frac{1}{14}\]
C) \[\frac{2}{3}\]
D) \[\frac{4}{21}\]
Correct Answer: C
Solution :
\[\frac{4}{5}\] of\[\text{5}\,\text{kg}\,\text{=}\frac{4}{5}\times \text{5}\,\text{=}\,\text{4}\,\text{kg}\]apples \[4\,\text{kg}\] apples were used on Monday. Now, apples left\[\text{= 5}\,\text{kg}-\text{4}\,\text{kg}\,\text{=}\,\text{1}\,\text{kg}\] Again, \[\frac{1}{3}\]of \[1\,\text{kg}\,\text{=}\,\,\frac{1}{3}\times 1=\frac{1}{3}\text{kg}\] apples \[\frac{1}{3}\text{kg}\] apples were used on next day. Apples left\[=1-\frac{1}{3}=\frac{3-1}{3}=\frac{2}{3}\,\,\text{kg}\text{.}\]
