If `( x- 3 )/5` - 2 = -1 , then x is equal to
( a )   8   ( b)  3   ( c )   -7  ( d )  2

If (x,3)+(2,5)=(7,8) then x is equal to a)2 b)5 c)7 d)9

If ( x + 3 , 4 - y ) = ( 1 , 7 ) , then ( x - 3 , 4 + y ) is equal to ( a ) ( -2 , -3 ) ( b ) ( -5 , 1 ) ( c ) ( 3 , 4 ) ( d ) ( 1, 5 )

If f(x) = | x | + [ x ] , then f( -3/2 ) + f( 3/2 ) is equal to : ( a ) 1 ( b ) -1/2 ( c ) 2 ( d ) 1/2

If a : b = 5 : 2 , then ( a - b )/b is equal to : ( A ) 7/2 ( B ) 3/5 ( C ) 3/2 ( D ) 2/3

If [(2x+y,0),(5,x)] = [(5,0),(5,3)] then y is equal to (a) 1 (b) 3 (c) 2 (d) -1

If a: b= 3:5 and b:c = 7:8, then 2a :3b: 8c is equal to

If log_(3){5+4log_(3)(x-1)}=2, then x is equal to 4 (b) 3 (c) 8 (d) log_(2)16

if f(x)=3|x|+|x-2| then f'(1) is equal to a)2 b)1 c)3 d)0

If x=3+sqrt(8), then x^(2)+(1)/(x^(2)) is equal to (a) 30 (b) 34(c)36 (d) 38

Let A=[1 2 3-5] and B=[1 0 0 2] and X be a matrix such that A=B X , then X is equal to 1/2[2 4 3-5] (b) 1/2[-2 4 3 5] (c) [2 4 3-5] (d) none of these
