$4 \frac{5}{6} - 5 \frac{5}{9} = ? - 2 \frac{1}{3} + \frac{11}{18}$

[UBI (PO), 2001]

$\frac{3}{4}$

$2 \frac{1}{18}$

$1 \frac{7}{9}$

$1 \frac{11}{18}$

None of these

Explanation

Here,

$= \frac{29}{6} - \frac{50}{9} = ? - \frac{7}{3} + \frac{11}{18} = \frac{87 - 100}{18} = ? - \frac{42 + 11}{18} = \frac{- 13}{18} + \frac{31}{18} = ? = \frac{18}{18} = ? o r 1 = ?$

Hence, Option D is correct.
