Solution

The correct option is E
None of these

$3 \frac{2}{7} - 2 \frac{3}{14} - 1 \frac{2}{7} = ? + 2 \frac{3}{14} ∴ ? = 3 \frac{2}{7} - 2 \frac{3}{14} - 1 \frac{2}{7} - 2 \frac{3}{14} = \frac{23}{7} - \frac{31}{14} - \frac{9}{7} - \frac{31}{14} = \frac{23}{7} - \frac{9}{7} - \frac{31}{14} - \frac{31}{14} = \frac{46 - 18 - 31 - 31}{14} = - \frac{34}{14} = - \frac{17}{7} = - 2 \frac{3}{7}$
