| When in each box 5 or 6 dozens of apples were packed, three dozens were left. Therefore, bigger boxes were taken to pack 8 or 9 dozens of apples. However still three dozens of apples remained. What was the least number of dozens of apples to be packed? |
A) 363 dozens
B) 315 dozens
C) 345 dozens
D) 335 dozens
E) None of these
Correct Answer: A
Solution :
| For such type of questions, remember the following method. |
| Required number of apples = LCM of \[(5,6,8,9)+3\] |
| \[\text{LCM}=2\times 3\times 5\times 4\times 3=360\] |
| Number of apples = 363 dozens |
