If `x : y=1:1,\ t h e n\ (3x+4y)/(5x+6y)=` (a) `7/(11)` (b) `(17)/(11)` (c) `(17)/(23)` (d) `4/5`

If x:y = 1:1, then (3x+4y)/(5x+6y) = ____.

If x:y=1:1, then (3x+4y)/(5x+6y)=(7)/(11) (b) (17)/(11)(17)/(23)(d)(4)/(5)

If (4x + 5) : (3x + 11) = 13:17, then (5x + 4): (4x -1) = ?

If (x)/(y)=(6)/(5), then the value of ((6)/(7)-(5x-y)/(5x+y)) is equal to (a) (1)/(7)( b) (2)/(7)(c)(3)/(7) (d) (4)/(7)

If (4x + 5) : (3x + 11) = 13:17 , then (5x + 4) : (4x -1) =?

The range of the function f(x)=(x^2+x+2)/(x^2+x+1),x in R , is (1,oo) (b) (1,(11)/7) (c) (1,7/3) (d) (1,7/5)

The range of the function f(x)=(x^2+x+2)/(x^2+x+1),x in R , is (a) (1,oo) (b) (1,(11)/7) (c) (1,7/3) (d) (1,7/5)

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

The range of the function f(x)=(x^2+x+2)/(x^2+x+1),x in R , is (1,oo) (b) (1,(11)/7) (1,7/3) (d) (1,7/5)
