Let \( A \) be the set of first \( 101 \) terms of an A.P., whose first term is \( 1 \) and the common difference is \( 5 \) and let \( B \) be the set of first \( 71 \) terms of an A.P., whose first term is \( 9 \) and the common difference is \( 7 \). Then the number of elements in \( A \cap B \), which are divisible by \( 3 \), is:
