Let S be a set of positive integers such that every element n of S satisfies the conditions

1. 1000 ≤ n ≤ 1200

2. every digit in n is odd

Then how many elements of S are divisible by 3?Let x=√4 + √4 - √4 + √4 - …. to infinity. Then x equals

The set of all positive integers is the union of two disjoint subsets:

{f(1), f(2), ......... f(n)...........}and {g (1), g (2),............g (n), ...........},

where f(1) < f (2) < ....... < f (n)......, and g (1) < g (2) < ..... < g (n) . .... . , and g (n)=f (n)+1 for all n ≥ 1.

What is the value of g (1) ?
