Answer & Solution
Correct Answer:
Option
D
Number of rotten apples :
$$\eqalign{ & = 30\% {\text{ of }}450 \cr & = \left( {\frac{{30}}{{100}} \times 450} \right) \cr & = 135 \cr} $$
∴ Number of good apples = 450 - 135 = 315
$$\eqalign{ & = 30\% {\text{ of }}450 \cr & = \left( {\frac{{30}}{{100}} \times 450} \right) \cr & = 135 \cr} $$
∴ Number of good apples = 450 - 135 = 315
