Question
Vishnu, Poorna, Vishal, Rajni, and Rama are sitting in a
line. Poorna is third to the extreme right end. Vishnu is second to the left of Poorna. Vishal is to the right of Poorna. Rajni is third to the right of Rama, who is the neighbor of Vishnu. Who is sitting at the center?Solution
 Poorna is third to the extreme right end. Vishnu is second to the left of Poorna. This implies that Vishnu sits at extreme left end.  Vishal is to the right of Poorna. Rajni is third to the right of Rama, who is the immediate neighbor of Vishnu. This means Rajni sits at the extreme right end, and Rama sits between Vishnu and Poorna. Final arrangement is shown below: From the above arrangement, it is clear that Poorna is sitting at the center. Hence, the correct answer is (A).
Quantity I: A vessel contains a mixture of milk and water in the ratio of 7 : 5. If 9 litre of mixture is sold and replaced by same amount of water then...
I. 2x² + 15 x - 27 = 0
II. 3 y² + 25 y - 18 = 0
I. 4p² + 17p + 15 = 0
II. 3q² + 19q + 28 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 32x + 207 = 0
Equation 2: y² - 51y + 648 = 0
I. x2 + (9x/2) + (7/2) = - (3/2)
II. y2 + 16y + 63 = 0
I.70x² - 143x + 72 = 0
II. 80 y² - 142y + 63 = 0
I. x2 – 13x + 40 = 0
II. 2y2 – 15y + 13 = 0Â
I. 7x² + 27x + 18 = 0
II. 19y² - 27y + 8 = 0
In the question, two equations I and II are given. You have to solve both the equations to establish the correct relation between 'p' and 'q' and choose...
l. x2 - 16x + 64 = 0
II. y2Â = 64
