Question
Statements: Some bricks are metals. All
metals are shiny. No shiny thing can float. Conclusions: (I) Some metals can float. (II) No brick can float. (III) Some bricks are shiny. In this question three statements are given followed by three conclusions I, II and III. You have to consider the three statements to be true even if they seem to be at variance from commonly known facts. Read all the conclusions and then decide which of the given conclusion(s) logically follow(s) from the given statements.Solution
The correct answer is B
The equations 6x + my + 18 = 0 and 9x + 21y + 27 = 0 have a unique solution. Which of the following statements is definitely true?
If 2x + 3y = 27 and 3x - y = 13, find (x + y).
I. 2p2 + 5p + 2 = 0Â Â Â Â Â Â Â Â II. 2q2 + 11 q + 14 = 0
I. p2 – 5p + 6 = 0                 Â
II. 36q2 = 81
