A. I alone sufficient while II alone not sufficient to answer B. II alone sufficient while I alone not sufficient to answer C. Either I or II alone sufficient to answer D. Both I and II are necessary to answer
Explanation: 2R = 44, according to I.H = 12 is the result of II.2RH = 2A = 2RH = 2RH = 2RH = (44 x 12).The price of the artwork is Rs (44 x 12 x 20).As a result, the solution is given by combining I and II.
