Question : 7 of 60

Marks: +1, -0

Guppy has a watch that shows the date without the month and the year. By default, the watch displays 31 days in each month. Therefore, at the end of all the months with less than 31 days the date on the watch needs to be readjusted. On 10th March 2001 it showed the right date as ‘10’. What date would it show on 15th May 2002, if it is known that Guppy never readjusted his watch during this period?

Validate

Solution:

On 1st April 2001, Guppy’s watch will correctly show the date as ‘1’ as March has 31 days only.
From 1st April 2001 to 30th April 2002 a total of 13 months or 365 + 30 = 395 days would have passed.
So the date shown by Guppy’s watch on 30th April, 2002 must be

395 - 12× 31 = 23

.
Subsequently his watch will show the date as ’24’ on 1st May, ‘1’ on 9th May and '7 ’ on 15th May, 2002.
