Solution:
To solve this problem, we need to calculate the total number of days from Ram's birthdate to the given date, and then find the corresponding day of the week. We can use the following steps:
Step 1: Find the number of days in 5 years, 2 months and 16 days
- 5 years = 5 x 365 = 1825 days (ignoring leap years)
- 2 months = 2 x 30 = 60 days (assuming 30 days per month)
- 16 days = 16 days
- Total number of days = 1825 + 60 + 16 = 1901 days
Step 2: Find the day of the week for Ram's birthdate
- March 20, 1992 was a Friday
- We can use the following formula to find the day of the week for any given date: (number of days from a known reference day) modulo 7
- For example, to find the day of the week for March 20, 1992: (0 + 31 + 19 + 31 + 30 + 31 + 20) modulo 7 = 5 (Friday)
- We add the number of days in each month (starting from January), and then add the day of the month (20 for March 20)
Step 3: Add the number of days to Ram's birthdate and find the corresponding day of the week
- To find the day of the week for 1901 days after March 20, 1992: (5 + 1901) modulo 7 = 6 (Saturday)
- Note that we add 5 (Friday) to 1901, and then take the remainder when divided by 7. This gives us the number of days after Friday, which is Saturday.
Therefore, Ram was 5 years, 2 months and 16 days old on Saturday.
