Answer 1

Step-by-step explanation:

LCM OF 3 AND 4 IS 12.

so he will have to take both of them on 12th day i.e. 14th October

Answer 2

Given: In a hospital every third day a patient is given tablets and every fourth day he is given an injection. He took both on 3rd October 1993.

To find: The next date on which he will again receive both of them

Explanation: Since on every third day a tablet is given and every fourth day an injection given, we need to find out the LCM of 3 and 4 to find the number of days after which both are given.

LCM of 3 and 4 = 3*4 = 12

Tablet and injection will be given every 12 days. After 3rd October 1993, the next 12th day will fall on (3+12)th October, that is 15th October.

Therefore, the patient will take both tablet and injection again on 15th October 1993.
