D)

The total salary amount = 30×1200=36000

The salary of the exiting supervisor = 1440

Therefore, the salary of 24 labours and the remaining 5 supervisors:

=36000-1440=34560

When a new supervisor joins, the new average salary drops to Rs.1160 for the total team of 30of them.

The total salary for the 30people i.e., 24 labours, 5old supervisors and 1 new supervisor = 1160×30= 34800

Therefore, the salary of the new supervisor is 36000-34800=1200 less than that of the old supervisor who left

the company, which is equal to 1440−1200=240
