Question
In a pack of 700 apples, 15% are found rotten. Find the number of good apples
- 105
- 700
- 600
- 595
Hint:
1. When a certain quantity is divided into 100 equal parts and a certain part of it is to be expressed in terms of the whole quantity, that portion is called as a percent, represented with a % sign.
2. Percentage of rotten apples = Number of rotten apples / Total number of apples * 100.
3. Total number of apples = Number of rotten apples + Number of pieces good apples.
The correct answer is: 595
Given-
Percentage of rotten apples = 15%
Total number of apples = 700
To find-
Number of good apples
Solution-
We know that-
Percentage of rotten apples = Number of rotten apples / Total number of apples * 100
∴ 15 = Number of rotten apples / 700 * 100
∴ 15 * 700 / 100 = Number of rotten apples
∴ 105 = Number of rotten apples ................................... (Equation i)
Total number of apples = Number of rotten apples + Number of pieces good apples.
∴ 700 = 105 + Number of good apples
∴ 700 - 105 = Number of good apples
∴ 595 = Number of good apples
Final Answer- Option 'd' i.e. '595' is the correct answer to the given question.
