Study the given arrangement and answer the question that follows:
W ↑ 2 S I * N 1 L @ = B D 3 6 ∆ H J 9 # 7 P K $ V & 8 4 M
If the symbols and numbers are interchanged serially as they appear in the arrangement such as ↑ with 2, * with 1, @ with 3 and so on, then which element will be the 17th element to the right of the 20th element from the right end in the new arrangement?
What do they mean, "symbols and numbers serially interchanged"? i dont understand someone explain this
