Answer & Solution
Correct Answer:
Option
C
Quantity of sugar
$$\eqalign{ & = \left( {\frac{4}{{100}} \times 6} \right)kg \cr & = 0.24\,\,kg \cr} $$
∴ New percentage :
$$\eqalign{ & = \left( {\frac{{0.24}}{5} \times 100} \right)\% \cr & = 4\frac{4}{5}\% \cr} $$
$$\eqalign{ & = \left( {\frac{4}{{100}} \times 6} \right)kg \cr & = 0.24\,\,kg \cr} $$
∴ New percentage :
$$\eqalign{ & = \left( {\frac{{0.24}}{5} \times 100} \right)\% \cr & = 4\frac{4}{5}\% \cr} $$
