Best answer
Correct Answer - Option 3 : Decrement, 4 : 3

Calculation :

Decrement in number of workers from 16 → 11

Increment in their wages from 11 → 12

Change in total wage from 16 × 11 → 11 × 12

∴ Ratio = 4 : 3 and  changes from 4 → 3 i.e. Decrement.

 Initial total wage = Initial no. of worker × their wage
