A) Monday | B) Tuesday |

C) Wednesday | D) Friday |

Explanation:

17th June, 1998 = (1997 years + Period from 1.1.1998 to 17.6.1998)

Odd days in 1600 years = 0

Odd days in 300 years = 1

97 years has 24 leap years + 73 ordinary years.

Number of odd days in 97 years ( 24 x 2 + 73) = 121 = 2 odd days.

Jan. Feb. March. April. May. June.

(31 + 28 + 31 + 30 + 31 + 17) = 168 days

168 days = 24 weeks = 0 odd day.

Total number of odd days = (0 + 1 + 2 + 0) = 3.

Given day is Wednesday.

A) Saturday | B) Monday |

C) Sunday | D) Tuesday |

Explanation:

If yesterday were tomorrow, today is Friday => tomorrow of friday is Saturday.

Hence, it implies that today is **Sunday** if tomorrow is Saturday.

A) 2000 | B) 2008 |

C) 2009 | D) 2012 |

Explanation:

Leap year means the year that can be divisible by 4. From the above options 2009 is not divisible by 4. So it is not a leap year.

A) Monday | B) Wednesday |

C) Thursday | D) Tuesday |

Explanation:

We know that,

Odd days --> days more than complete weeks

Number of odd days in 400/800/1200/1600/2000 years are **0.**

Hence, the number of odd days in first 1600 years are 0.

Number of odd days in 300 years = 1

Number of odd days in 49 years = **(12 x 2 + 37 x 1) = 61 days = 5 odd days**

Total number of odd days in 1949 years = **1 + 5 = 6 odd days**

Now look at the year 1950

Jan 26 = 26 days = **3 weeks + 5 days = 5 odd days**

Total number of odd days = **6 + 5 = 11 => 4 odd days**

**Odd days :- **

0 = sunday ;

1 = monday ;

2 = tuesday ;

3 = wednesday ;

4 = thursday ;

5 = friday ;

6 = saturday

Therefore, **Jan 26th 1950** was **Thursday.**

A) October, December | B) April, November |

C) June, October | D) April, July |

Explanation:

If the period between the two months is divisible by 7, then that two months will have the same calender .

(a). Oct + Nov = 31 + 30 = 61 (not divisible by 7)

(b). Apr + May + Jun + Jul + Aug + Sep + Oct = 30 + 31 + 30 + 31 + 31 + 30 + 31 = 214 (not divisible by 7)

(c). Jun + July + Aug + Sep = 30 + 31 + 31 + 30 = 122 (not divisible by 7)

(d). Apr + May + June = 30 + 31 + 30 = 91 (divisible by 7)

Hence, April and July months will have the same calendar.

A) 31523500 sec | B) 315360000 sec |

C) 315423000 sec | D) 315354000 sec |

Explanation:

We know that,

1 year = 365 days

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds.

Then, 1 year = 365 x 24 x 60 x 60 seconds.

= 8760 x 3600

1 year = 31536000 seconds.

Hence, **10 years = 31536000 x 10 = 315360000 seconds.**

A) Saturday | B) Sunday |

C) Friday | D) Thursday |

Explanation:

The day of the week repeats every 7 days.

Given today is Friday. Again Friday is repeated on the 7th day, 14th,... on 7 multiple days.

Hence, Friday is on the 63rd day, as 63 is multiple of 7.

Now, the required day of the week on the 65th day is **Sunday.**

A) same day | B) previous day |

C) next day | D) None |

Explanation:

We know that the day repeats every 7 days, 14 days, 21 days,...

So if today is Monday, after 7 days it is again Monday, after 14 days again it is Monday.

Hence, after 2 weeks i.e, 14 days the day repeats and is the same day.

A) 22 | B) 23 |

C) 24 | D) 25 |

Explanation:

Calculating Age has 2 conditions. Let your Birthday is on January 1st.

1. If the month in which you are born is completed in the present year i.e, your birthday, then

Your Age = Present year - Year you are born

As of now, present year = 2018

**i.e, Age = 2018 - 1995 = 23 years.**

2. If the month in which you are born is not completed in the present year i.e, your birthday, then

Your Age = Last year - Year you are born

As of now, present year = 2018

**i.e, Age = 2017 - 1995 = 22 years.**
