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

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

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