compute the following material variances contributing to the actual cost of 100 kg o 621599

The standard material cost for 100 kg of Chemical D is made up of:

Chemical A	30 kg @ Rs. 4.00 per kg
Chemical B	40 kg @ Rs. 5.00 per kg
Chemical C	80 kg @ Rs. 6.00 per kg

In a batch, 500 kg of Chemical D is produced from a mix of:

Chemical A	140 kg at a cost of Rs. 588
Chemical B	220 kg at a cost of Rs. 1,056
Chemical C	440 kg at a cost of Rs. 2,860

Compute the following material variances contributing to the actual cost of 100 kg of Chemical D over the Standard Cost: (i) MCV; (ii) MPV; (iii) MUV; (iv) MMV; (v) MYV.
