Solution



To find:
    • The number of basic units of currency X, which are equivalent to 250 basic units of currency Y

Analysing Statement 1
    • As per the information given in statement 1, 100 basic units of currency X are equivalent to 625 basic units of currency Y
      o Therefore, 250 basic units of currency Y = \(\frac{100}{625} * 250\)

Hence, statement 1 is sufficient to answer

Analysing Statement 2
    • As per the information given in statement 1, 2000 basic units of currency X are equivalent to 12500 basic units of currency Y
      o Therefore, 250 basic units of currency Y = \(\frac{2000}{12500} * 250\)

Hence, statement 2 is sufficient to answer

Hence, the correct answer is option D.

Answer: D

It is interesting to notice that both answer choices basically say the same, because statement two is a multiple of statement one (factor 20).

I am still choosing D, because a currency conversion is always a straight line. e.g. 1 EUR = 1,15 USD. Therefore, 2 EUR = 2,30 USD. The same reasoning applies to this question.

Answer should be E right ? We can't find the relation if its a straight line or parabola or anything else? Even with both the statements included. Please help.

Hello

I think in this case relation should be fairly simple and straight (line). If 'a' units of currency X are equal to 'b' units of currency Y, then
1 unit of currency X = b/a units of currency Y and
1 unit of currency Y = a/b units of currency X
