(a) Sunday
(b) Monday
(c) Tuesday

Answer 1

Ramesh will need to bring the bike for servicing on a Monday.

Step-by-step explanation:

To find the day of the week after a certain number of months, we need to consider that each year has 12 months, so 30 months is equal to 2 years and 6 months. Additionally, we need to account for the leap years if applicable.

Since Ramesh bought the bike on a Tuesday, we need to find the day of the week that falls 2 years and 6 months later.

We know that a non-leap year has 52 weeks and 1 day (365 days), whereas a leap year has 52 weeks and 2 days (366 days).

1. First, we find the total number of days: 2 years * 365 days/year + 1 leap day/year + 6 months * 30 days/month = 730 + 1 + 180 = 911 days.
2. Next, we divide the total number of days by 7 (the number of days in a week) to find the remainder. In this case, 911 divided by 7 gives a remainder of 6.
3. We add the remainder to the starting day of Tuesday, which gives us 6 days after Tuesday.

Based on this calculation, the bike will need to be brought for servicing 6 days after Tuesday, which means it will fall on a Monday.
