Explanation
There are 4 numbers in S and 5 numbers in T, so the total number of possible products that can be formed using one number in each set is (4)(5), or 20. However, some of these products have the same value; for example, (1)(8) = (4)(2). Therefore, Quantity A, the number of different possible values of the product xy, is less than Quantity B, 20. Thus the correct answer is Choice B.

S = {1, 4, 7, 10} T = {2, 3, 5, 8, 13}
\(x\) is from set \(S\) & \(y\) is from set \(T\)
Qt A
Different Possible values of \(xy\) \(= 2, 3, 5, 8, 13, 12, 20, 32, 52, 14, 21, 35, 56, 91, 30, 50, 80, 130\)
\(8\) & \(20\) will be repeated hence they are taken once only. Total no \(= 18\)
Qt B > Qt A
