If `a/b=4/3` , then `(3a+2b)/(3a-2b)=?` (a) `-1` (b) 3 (c) 5 (d) 6

If a/b=4/3, then the value of (6a+4b)/(6a-5b) is -1 (b) 3 (c) 4 (d) 5

If a+b=5 and 3a+2b=20, then (3a+b) will be: (a)10 (b) 15 (c) 20 (d) 25

If (4b^(2)+(1)/(b^(2)))=2, then (8b^(3)+(1)/(b^(3)))=? (a) 0 (b) 1 (c) 2 (d) 5

If x+2 is a factor of x^2+a x+2b and a+b=4 , then (a) a=1, b=3 (b) a=3, b=1 (c) a=-1, b=5 (d) a=5, b=-1

If a:b:c=2:3:4, then (1)/(a):(1)/(b):(1)/(c) is equal to (1)/(4):(1)/(3):(1)/(2) b.4:3:2 c.6:4:3 d.none of these

If [(2a+b,a-2b),(5c-d,4c+3d)]=[(4,-3),(11,24)] then the value of a+b-c+2d is (a) 8 (b) 10 (c) 4 (d) -8

If a=2b, then a:b=2:1 (b) 1:2( c) 3:4 (d) 4:3

If (a+b+2c+3d)(a-b-2c+3d)=(a-b+2c-3d)(a+b-2c-3d) , then 2b c is equal to 3/2 (b) (3a)/(2d) (c) 3a d (d) a^2d^2

If a : b = 2: 5 , then ( 3a+ 4b) : (5a +6b) is equal to

The common difference of the A.P. 1/(2b),(1-6b)/(2b),(1-12 b)/(2b),... is 2b (b) -2b (c) 3 (d) -3
