If A and B are two sets given in such a way that `AxxB` consists of 6 elements and if three elements of `AxxB` are (1,5), (2,3) and (3,5), what are the remaining elements?

Text Solution

Verified by Experts

Since, (1,5),(2,3),(3,5) `in A xx B`, then clearly `1,2,3inA` and `3,5inB`.
`AxxB={1,2,3}xx{3,5}`
`=(1,3),(1,5),(2,3),(2,5),(3,3),(3,5)`
Hence, the remaining elements are (1,3), (2,5), (3,3).
