If `1/3+1/2+1/x=4` , then `x=?` `5/(18)` (b) `6/(19)` (c) `(18)/5` (d) `(24)/(11)`

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

When ((1)/(2)-(1)/(4)+(1)/(5)-(1)/(6)) is divided by ((2)/(5)-(5)/(9)+(3)/(5)-(7)/(18)), the result is 2(1)/(18) (b) 3(1)/(6)(c)3(3)/(10) (d) 5(1)/(10)

If (5/3)^(-5)xx(5/3)^(11)=(5/3)^(8x) , than x=? (a) -1/2 (b) -3/4 (c) 3/4\ \ (d) 4/3

(3)/(4)+2(1)/(4) of (2)/(3)-((1)/(2)-(1)/(3))/((1)/(2)+(1)/(3))xx3(1)/(3)+(5)/(6)=?(7)/(18)(b)(49)/(54)(c)(2)/(3)(d)(1)/(6)

The maximum value of f(x)=(x)/(4-x+x^(2)) on [-1,1] is (a) (1)/(4)(b)-(1)/(3)(c)(1)/(6)(d)(1)/(5)

If 4x+3y=18xy and 2x-5y+4xy=0 then the values of x and y will be respectively -(1)/(2) and -(1)/(3)(b)-1 and -3(c)(1)/(2) and (1)/(3) (d) (1)/(4) and (1)/(3)

5(5)/(6)-3(8)/(9)-?=1(2)/(3)(b)(3)/(2)(c)(17)/(18) (d) 3

3+(x)/(4)=(1)/(2)(4-(x)/(3))-(5)/(6)+(1)/(3)(11-(x)/(2))
