If `(-3)/7=x/(35),` then `x=` (a)15 (b) 21 (c)`-15` (d) `-21`

If 4x+5y=83 and (3x)/(2y)=(21)/(22), then y-x=?( a) 3( b) 4 (c) 7 (d) 11

If 4/7 of 49% of x is 21, then x= (a) 125 (b) 98 (c) 84 (d) 75

If the mode of 22 ,\ 21 ,\ 23 ,\ 24 ,\ 21 ,\ 20 ,\ 23 ,\ 26 ,\ x and 26 is 23, then x= (a) 20 (b) 21 (c) 23 (d) 24

If the mean of 6,\ 7,\ x ,\ 8,\ y ,\ 14 is 9, then (a) x+y=21 (b) x+y=19 (c) x-y=19 (d) x-y=21

If the mean of 6,\ 7,\ x ,\ 8,\ y ,\ 14 is 9, then (a) x+y=21 (b) x+y=19 (c) x-y=19 (d) x-y=21

In the given figure, if A B || C D , the value of x is (a) 25 (b) 35 (c) 15 (d) 20

On subtracting -7 from -14 , we get (a) -21 (b) -7 (c) -14 (d) 21

The sum of two consecutive odd number is 36. The larger number is (a)17 (b) 15 (c)19 (d) 21

Let x,y,z are positive reals and x +y+z=60 and x gt 3. Maximum value of (x-3) (y+1) (z+5) is : (a) (17) (21) (25) (b) (20) (21) (23) (c) (21) (21)(21) (d) (23)(19) (15)

If the events A and B are independent and if P(bar(A) ) = (2)/(3) , P(bar(B)) = (2)/(7) , then P(A cap B) is equal to a) 4/21 b) 3/21 c) 5/21 d) 2/21
