Option a) 128 X 32 Y 120 Z 64 W 16
New Expression: 128 × 32 + 120 − 64 ÷ 16 
= 128 × 32 + 120 − 4
= 4096 + 120 − 4
= 4216 − 4
= 4212 (Incorrect)
Option b) 128 W 32 Z 120 Y 64 X 16
New Expression: 128 ÷ 32 − 120 + 64 × 16
= 4 − 120 + 64 × 16
= 4 − 120 + 1024
= 1028 − 120 
= 908 (Correct)
Thus, correct option is (b).
