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.

In an election only two candidates contested 20% of the voters did not vote and 120 votes were declared as invalid.

A) 47.5% B) 41%
C) 38% D) 45%

      0.8x - 120 = k + (k + 200)

 

         k+200 = 0.41x

 

 => k = 1440

 

and  (k + 200) =1640

 

Therefore  1440/3200 x 100 = 45%
