Rewrite the terms: (2-1)*1!+(3-1)*2!+..........+(101-1)*100!= 101!-1! When this is divided by 202, the remainder is -1, which implies the remainder is 201.

If increasing 20 by P percentage gives the same result as decreasing 60 by P percentage,What is P percentage of 70?
Increasing 20 by P% => x=20+20.P/100 Decreasing 60 by P% => y=60-60.P/100 Acoording to the question, x=y => 20+20.P/100=60-60.P/100 Solving we get P=50 So, P% of 70=50% of 70=35 So, answer is 35
