If we take the LCM of 2, 4 and 6 hours then got 12 hours.

In 12 hours alarms ring simultaneously once.

It means 12 hours = 1.

Hence 3 days = 72 hours = 6.

Angle between the hands of a clock is given by the formula $\dfrac{11}{2}H – 30M$ or $30M – \dfrac{11}{2}H$ where H is hours and M is minutes.
Here, Given time = 02 : 30, H = 2 and M = 30.
Angle = $\dfrac{11}{2} \times 30 – 30 \times 2 = 165 – 60 – 105^\circ$

2016 is a lead year. So it has 366 days. If we convert them into week then got 52 weeks and 2 days.

So P = 2 days.

There are 7 years between the two except two of them are leap years.

In a normal year, there are 365 days. 365 when divided by 7 leaves a reminder of 1. So, 1 July of a year and 1 July of the previous year are one weekday apart. If it is a leap year, 1 July of a year and 1 July of a previous year are separated by 2 weekdays. So, If July 1, 1977 was a Friday, 1st july 1976 is a Thursday and 1st july 1975-tuesday 1st july 1974-monday 1st july 1973-sunday 1st july 1972-saturday 1st july 1971-thrusday 1st july 1970- wednesday

Number of days from 25th January 2015 to 24th January 2016 is 365 days.
Subtracting 365 days from 554 days => 189 days
Subtracting remaining days from January which are 7 days => 182 days
Subtracting the number of days in February, March, April, …. till we get 0
182-29-31-30-31-30-31 = 0
Till July 31st, we get 0.
Hence, August 1st, 2016 will be 554 days after 25th January 2015.

Every year one day will be increased. But in leap year 2 days will be increased. So for increasing 7 days, we have to go upto 2024. So on $5^{th}$ January 2024 that day will be repeated.
