Answers
Answer:
2nd October 1933 is the answer
Given: In a hospital every third day a patient is given tablets and every fourth day an injection is given. On 3rd October 1993 he had both.
To find: On which other days in October 1993,he will have get both tablets and injection
Explanation: Since every third day he gets medicine and every fourth day he gets injection, the day when he gets both is the LCM of 3 and 4.
LCM of 3 and 4 = 3*4 = 12
Therefore, he gets both every 12th day.
He gets both on 3rd October 1993. The second time he gets both is (3+12)th October, that is 15th October 1993.
The third time he gets both in October is 12 days after 15th October, that is 27th October 1993.
Therefore, the two more days in October 1993 when he gets both of them is 15th October 1993 and 27th October 1993.
