Question

If the first day of the year 1990 was a Monday what day of the week was 1st January 1998?

• A. Thursday
• B. Tuesday
• C. Wednesday
• D. Friday

Answer 1

Answer: (A)

Thursday

IN the leap year odd no. of day in the year $=2$

Leap year has $29$ day in feb.

The Leap in that divided by $4$

So,

$1990=1$

$1991=1$

$1992=2$

$1993=1$

$1994=1$

$1995=1$

$1996=2$

$1997=1$

$1998=1$

$(1+1+2+1+1+1+2+1+1)=11$

The odd no. of the year $=$ No. of day in year $7$

$11$/$7$=$4$

Remainder=$4$

So, $4$=TUESDAY

Hence, this is the answer.
