Answer VerifiedHint:: To solve this type of problem first of all we have to calculate the total no. of rotten apples in the basket and then to calculate the final answer that means, total no. of apples. For getting that, we have to add the total no. of rotten apples and good apples i.e.,Total no. of apples = No. of good apples + no. of rotten apples. Complete step by step solution: $\therefore$ The total no. of apples will be $75$. Hence, the correct option is (A). Note: First of all, read the question carefully to understand what they asked for. We can use two different methods to calculate the answer to this type of question This method is easier and understandable than any other method. Alternative method: To solve the problem, we need to find the no. of rotten apples using a given percentage of it in total no. of apples & then add it to the no. of good apples to get the total no. of apples in the basket.$12\% $ of total no. of apples – \[Percentage{\text{ }}of{\text{ }}rotten{\text{ }}apples{\text{ }} \times {\text{ }}no.{\text{ }}of{\text{ }}good{\text{ }}apples{\text{ }}/{\text{ }}percentage{\text{ }}of{\text{ }}good{\text{ }}apples\] \[12 \times \dfrac{{66}}{{88}} = 12 \times \dfrac{3}{4} = 3 \times 3 = 9\] Now, Total no. of apples = no. of rotten apples + no. of good apples $ = 9 + 66 = 75$ So, you can use either of these methods to get the answer according to your convenience but make sure you don’t make a mistake in calculations.
