Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

option 3 , labour yield variance is the right answer. (actual yield minus standard yield multiplied by standard unit cost)
I think something is wrong with your formula because LRV = AH(SR-AR) and same problem with other formula also. So please confirm it.
See, the difference between actual data & standard data is the VARIANCE. It can be favourable or unfavorable. When actual yield or output is more than standard yield, the variance is favourable and adverse in vice- versa. When actual labour cost exceeds std labour cost , it is said to be unfavourable. So, I think we can write the formula this way also and then do the variance analysis for remedial actions.
