Anser is C) only member of the given set....
answer of this question is 17.
Sol.
given set={1,4,7,...,97,100}.
counting from 1 and reverse counting from 100 till 53 gives 17.
answer of first qs. is single digit.
because 2*5=10 and 10*10=100,this 100 is cancelled out by two 0's of 1000.
i think ans. should be 4 or 6, but i am getting 8.
