COMPUTE the missing data indicated by the question marks from the following: Particulars A B Standard Price/ unit 12 15 Actual Price/ unit 15 20…

(a) (i) Standard input (kgs.) of Material- B: Material usage variance = Std. Rate (Std. Quantity – Actual Quantity) 300 Adverse = 15 (SQ – 70) Or, -300 = 15 SQ – 1,050 Or, SQ = 50 kgs. (ii) Actual Input (kgs) of Material- A: Let the actual input in for Material-A is X kgs. Material Mix Variance = Std. Price (Actual Quantity in Std. mix – Actual Quantity) Or, Material Mix Variance (A+B) = Material Mix Variance for Material - A + Material Mix Variance for Material -B Or, -45 = [12{(X+70)/2 - X}] + [15{(X+70)/2 - 70}] Or, -45 = [12{(X+70-2X)/2}] + [₹ 15{(X+70-140)/2}] Or, -45 = [₹ 12{(70-X)/2}] + [15{(X-70)/2}] Or, -45 = [-6X+420] + [(15X-1,050)/2] Or, -45 = [(-12X+840+15X-1,050)/2] Or, -90 = 3 X-210 Or, 3X = 120 X = 40 kgs. (iii) (a) Material Price Variance of A = Actual Quantity (Std. Rate – Actual Rate) = 40 kg. (12-15) = 120 Adverse (b) Material Price Variance of B = 70 kg. (15 – 20) = 350 Adverse (iv) Material usage variance of A = Std. Rate (Std. Quantity – Actual Quantity) = 12 (50 – 40) = 120 Favourable (v) (a) Material Cost variance of A = Std. Cost - Actual Cost = (50 kgs. @12) – (40 kgs. @15) = 600 - 600 = Nil (b) Material Cost variance of B = (50 kgs. @15) – (70 kgs. @20) = 750 – 1,400 = 650 Adverse
