Explanation:
The standard kgs permitted[tex]= 3100 \times 0.62 = 1922[/tex]
Current production Standard cost permitted [tex]=1922\times 7= 13454[/tex]
Variance of materials for expenditure [tex]= 13708-13454= 254 \ \ \ U[/tex]
Outlined various of materials [tex]= 13708-(2077\times 7)= 831 \ \ \ F[/tex]
Variability of additional channel [tex]= 7\times (2077-1922)= 1085\ \ \ U[/tex]
