A) Friday | B) Saturday |

C) Sunday | D) Thursday |

Explanation:

**15 Aug, 1947** = (1946 years + Period from 1.1.1947 to 15.8.1947)

**Odd days** in 1600 years = 0

**Odd days** in 300 years = 1

**46 years** = (35 ordinary years + 11 leap years) = (35 x 1 + 11 x 2)= 57 (8 weeks + 1 day) = **1 odd day **

**Jan. Feb. Mar. Apr. May. Jun. Jul. Aug **

( **31 + 28 + 31 + 30 + 31 + 30 + 31 + 15** ) = 227 days = (32 weeks + 3 days) = **3 odd days.**

**Total number of odd days = (0 + 1 + 1 + 3) = 5 odd days. **

Hence, as the number of **odd days = 5 , given day is Friday.**

A) Wednesday | B) Thursday |

C) Tuesday | D) Monday |

A) Tuesday | B) Monday |

C) Wednesday | D) Sunday |

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.**
