Answers & Solutions:
1) Answer (A)
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.
2) Answer (D)
3) Answer (C)
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 = $\dfrac{11}{2} \times 30 – 30 \times 2 = 165 – 60 – 105^\circ$
4) Answer (B)
5) Answer (B)
6) Answer (A)
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.

7) Answer (A)
8) Answer (A)
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
9) Answer (C)
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.
10) Answer (C)
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.
