Question
If a rope is cut into 3 pieces of unequal length, what
is the length of the shortest of these pieces? I. The combined length of the 2 longer pieces of the rope is 12 m. II. The combined length of the 2 shorter pieces of the rope is 10 m. Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer –ÂSolution
‘x’, ‘y’, ‘z’ be the lengths of the ropes is in the increasing order of length. Then from statement I, x + z = 12 and from statement II, x + y = 10 2 equations and 3 variables. Thus, cannot get ‘x’.
