n/7 = q+r
n = 7q+r (q->quotient r->remainder)
Whats is r? (could be 0,1,2,3,4,5,6)
Stmt I
n/21 is odd integer(1,3,5,7....)
Consider remainder =1 ,3 case
n/21 = q+1 or n/21 = q + 3 and so on....
n=21q+1 or n= 21q+3
Take q=0
n=1 or n=3
Divide by 7 gives 2 remainder values
INSUFF
Stmt II
n/28 = q+3
n=28q+3
q=0 n=3 3/7 remainder 3
q=1 n = 31 31/7 remainder 3
q=2 n=59 59/7 remainder 3
q=3 n = 87 87/7 remainder 3
It follows a pattern where the remainder will always be 3
ONE DEFINITE ANSWER
SUFF
B)
