Solution

The correct option is B $3 (4 y + 3 z)$
$R a m^{'} s t o t a l d e p o s i t i n 3 m o n t h s i s - (2 x - y + z) + (x + 6 y + 3 z) + (x + 4 z) = 4 x + 5 y + 8 z - - - - (a) H i s t o t a l w i t h d r a w a l i s - (x - y - z) + (x - 6 y + 3 z) + 2 x - 3 z = 4 x - 7 y - z - - - - (b) ∴ H i s b a l a n c e i s a - b = 12 y + 9 z = 3 (4 y + 3 z)$
