Question
Seven boxes viz. A, B, C, D, E, F and G are kept one
above other in the form of stack. How many boxes are kept above box E? I. Only two boxes are kept between box B and box F. Only three boxes are kept above box D. Box B and D are kept together. Only one box is kept between box E and box G. Box A is neither kept at bottom nor adjacent to box B. II. Box C is kept second from top. Box E is kept at any place above box G. Only three boxes are kept between box F and box C. Box D, which is neither kept adjacent to box C nor box F, which is kept at a gap of two box from A. Box B doesn’t kept adjacent to box F but kept at any place below box A. Each of the questions below consists of a question and three statements numbered I, II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question:Solution
From I: We have:Â Only three boxes are kept above box D. Box B and D are kept together. Only two boxes are kept between box B and box F Only one box is kept between box E and box G. Box A is neither kept at bottom nor adjacent to box B, that means box A is kept at top and box F is kept below box B. Based on above given information we have:
LCM of 'x' and 'y' is 30 and their HCF is 1 such that {10 > x > y > 1}.
I. 2p²- (x + y) p + 3y = 0
II. 2q² + (9x + 2) = (3x + y) q
I. 96x² + 52x - 63 = 0
II. 77y² + 155y + 72 = 0
I. 10p² + 21p + 8 = 0
II. 5q² + 19q + 18 = 0
I. 8x² + 2x – 3 = 0
II. 6y² + 11y + 4 = 0
If the roots of the quadratic equation 6m² + 7m + 8 = 0 are α and β, then what is the value of [(1/α) + (1/β)]?
I. 27x6 - 152x3 + 125 = 0
II. 216y6 - 91y3 + 8 = 0
I. x2 + 13x + 42 = 0
II. y² + 13y + 40 = 0
How many values of x and y satisfy the equation 2x + 4y = 8 & 3x + 6y = 10.
Let 's' represent the sum of the highest root of equations I and III, and 'r' denote the product of the lowest root of equation I and the highest root o...
I. 8x2 - 2x – 15 = 0
II. 12y2 - 17y – 40 = 0
