What is 90 days from today?

 

Hints : Today is 20th January 2017, Sunday

A) 18th April, Friday B) 20th April, Saturday
C) 21th April, Sunday D) 19th April, Saturday
 
Answer & Explanation Answer: B) 20th April, Saturday

Explanation:

Given Today is 20th January 2017, Sunday

In january, we have 31 days

February - 28 days (Non leap year)

March - 31 days

April - 30 days

=> Remaining days => 31 - 20 = 11 in Jan

+ 28 in Feb + 31 in Mar = 11 + 28 + 31 = 70 days

More 20 days to complete 90 days => upto 20th April

 

Therefore, after 90 days from today i.e, 20th Jan 2017 is 20th Apr 2017.

 

Now, the day of the week will be 

90/7 => Remainder '6'

As the day starts with '0' on sunday 

6 => Saturday.

 

Required day is 20th April, Saturday.

Q:

Pick the odd man out of the folowing number sequence?

123 112 133 112 143

A) 143 B) 122
C) 133 D) 112
 
Answer & Explanation Answer: B) 122

Explanation:

Here the given series is 123 112 133 112 143

It follows a pattern that,

123

123 - 11 = 112

112 + 21 = 133

133 - 31 = 102 (not 122)

102 + 41 = 143

 

Hence, the odd man in the given number sequence is 122 instead of 102.
