Question

Rama took 30 days to complete an English speaking course. The course was
completed on 15th January. When did Rama join the course.​

Answer 1

Answer:

17th December

Step-by-step explanation:

Since 15 days of course was done in January, therefore the first 15 days were in December,

so 31st December - 15 days = 16th December

Now 16th December is the date just before Rama joined the course (as we subtracted all the days of the course)

The next day after 16th Dec is 17th December, which would be the first day of the course.
