In how many different ways can six players be arranged in a line such that two of them, Asim and Raheem are never together?A. 120
B. 240
C. 360
D. 480
Explanation:
1. As there are six players, So total ways in which they can be arranged = 6!ways =720.
A number of ways in which Asim and Raheem are together = 5!x2 = 240.
Therefore, Number of ways when they don’t remain together = 720 -240 =480.The value of 25.25 – 23.23 + 24.24 is_________?

The successive discounts 20% and 15% are equal to a single discount of__________?A. 35%
B. 38%
C. 32%
D. 29%
E. None of these
Explanation:
Let the CP of an article be Rs. 100
Given that successive discounts are 20% and 15%.
SP = 85% of 80% of 100 = (85/100)(80/100)(100)
=> SP = Rs. 68
Clearly, single discount is 32%.I. x2 + 11x + 30 = 0, II. y2 + 15y + 56 = 0 to solve both the equations to find the values of x and y?
I. x2 + 11x + 30 = 0,
II. y2 + 15y + 56 = 0 to solve both the equations to find the values of x and y?A. If x < y
B. If x > y
C. If x ≤ y
D. If x ≥ y
Explanation:
I. x2 + 6x + 5x + 30 = 0
=>(x + 6)(x + 5) = 0 => x = -6, -5
II. y2 + 8y + 7y + 56 = 0
=>(y + 8)(y + 7) = 0 => y = -8, -7
