05. From the following details, calculate material variances
Standard Actual
Production in units 2,000 1,800
Materials per unit:
Max 4 kg @ Rs. 12/kg 5.6 kg. @ Rs. 14/kg
Dax 2 Kg @ Rs. 6/kg 2.8 kg. @ Rs. 5/kg

Solution
[TMCV = − Rs. 58,320; TMPV = − Rs. 15,120; TMUV/MQV = − Rs. 43,200; TMMV = Nil ; TMYV/MSUV = − Rs. 43,200;]

06. From the following figures given to you, calculate material variances. Production for the period 184 units:

Material X Material Y
Standard Price Per Ton Rs. 240 Rs. 320
Actual Price Paid per Ton Rs. 230 Rs. 308
Actual Weights 15 tons 13 tons
The standard production for the period represented by the above figures is 400 units for which the standard quantity allowance for material are 39 tons of X and 25 tons of Y.

Solution
[TMCV = + Rs. 531.60; TMPV = + Rs. 306; TMUV/MQV = + Rs. 225.60;
TMMV = − Rs. 165; TMYV/MSUV = + Rs. 390.60; ]

07. The standard quantity and standard price of raw material required for one unit of a product are given as follows:

Quantity SP
Material I 3 kg. Rs. 4 per kg.
Material II 5 kg. Rs. 3 per kg.
Total
 8 kg.

The actual production and relevant data are as follows:

Output 500 units of the Product

Material Total Quantity
for 500 units
Total cost
Rs.
I 1,600 kg. 6,880
II 2,400 kg. 7,440

Caluculate variances.

Solution
[TMCV = − Rs. 820; TMPV = − Rs. 720; TMUV/MQV = − Rs. 100; TMMV = Nil ;TMYV/MSUV = − Rs. 43,200;]

08. ABC Ltd. uses the following standard and actual mix of their compound in one batch of its production line:

Materials Standard mix
(kg)
Standard rate
(Rs. per kg)
Actual Mix
(kg)
P 50 2.00 460
Q 30 3.00 540
R 20 4.00 710
Total 100 1,710

Calculate Material mix sub-variance (MMSV)

Solution
[TMCV = – TMPV = – TMUV/MQV = – TMMV = − Rs. 736; TMYV/MSUV = –]

09. Saw Pipes Ltd manufactures a product known as the M 100 by mixing two materials. The standard material cost per unit of the M 100 is as follows.

Rs.
Material P 12 lts @ Rs. 12.50/ltr 150
Material Q 18 lts @ Rs. 15.00/ltr 270

In March, the actual mix used was 984 litres of P and 1230 litres of Q. The actual output was 72 units of M 100.
