What is the value 120 $ 12 * 6 # 2 ?

Statement (I) : MeansMeans\div$, * means X and # means +.

Statement (II) : 16 $ 4 * 2 # 2 = 10

Decide whether the data provided in the statements are sufficient to answer the question.

Solution

Correct Option: 4

Statement I directly defines the symbols, giving 120÷12×6+2=62120\div 12\times 6+2=62. Statement II: testing symbol assignments, only \=\div,, *=\times,, #=+producesproduces16\div 4\times 2+2=10$. So Statement II also uniquely determines the symbols. Either statement alone is sufficient.
