7).If 1!+2!+3!+4!+………+100! Is divided by 8, then
the remainder is
a)1
b)2
c)3
d)5
Answer: a)
Explanation:
.└2 is exactly divisible by 2.
└3 is exactly divisible by 3.
└4 is exactly divisible by 4.
Hence,└n is divisible by n.
(n!=1×2× 3 ×4 …..(n-1)× n)
∴ └8+└9+└10+……..└100
Is divisible by 8
Now, └1+└2+└3+……..+└7
=1+2+6+24+120+720+5040 =5193
∴Required remainder =Remainder obtained on dividing 5913 by 8 =1
