Sohan celebrated his birthday on Monday in 1992 . If his birthday falls on 7^th September, when will he celebrate his birthday in 2012?

Friday

Difference in between  2012 & 1992  = 2012 – 1992  =  20

Number of leap yeas   =  5 ( leap year in 2012 is also counted  & leap year in year 1992 is not counted )  

Total = 20 + 5 =  25

Now , \(\frac{25}{7}\)

Remainder = 5

 ⸫  5 days ahead of Monday

So, answer is  Friday
