Solution

Correct option : B. 107.872
Ratios of atomic mass on old scale = ratio of atomic mass on new scale
Hence
$\frac{A t o m i c m a s s o f s i l v e r o n o l d s c a l e}{A t o m i c m a s s o f o x y g e n o n o l d s c a l e} = \frac{A t o m i c m a s s o f s i l v e r o n n e w s c a l e}{A t o m i c m a s s o f o x y g e n o n n e w s c a l e}$
$H e n c e a t o m i c m a s s o f s i l v e r o n o l d s c a l e = \frac{A t o m i c m a s s o f s i l v e r o n n e w s c a l e \times A t o m i c m a s s o f o x y g e n o n o l d s c a l e}{A t o m i c m a s s o f o x y g e n o n n e w s c a l e}$
$a t o m i c m a s s o f s i l v e r o n o l d s c a l e = \frac{107.868 \times 16.00}{15.994}$
$A t o m i c m a s s o f s i l v e r o n o l d s c a l e = 107.872$
