| A crate of apples contains one bruised apple for every 30 apples in the crate. If 3 out of every 4 bruised apples are considered unsalable and there are 12 unsalable apples in the crate, then how many apples are there in the crate? |
A) 480
B) 270
C) 600
D) 740
Correct Answer: A
Solution :
| 1 crate has 1 bruised apple for every 30 apples. |
| 3 out of 4 are considered as unsalable, then for 3 unsalable apples, total apples \[=30\times 4=120\] |
| Similarly, for 12 unsalable apples. |
| Total apples \[=4\times 120=480\] |
| Alternate Method |
| Unsalable apples be \[x.\] |
| \[3:4::12:x\] |
| \[\Rightarrow \] \[x=16\] |
| \[\therefore \]Total number of apples \[=16\times 30=480\] |
