Sipalo Ltd manufacturer product X using three differnt materials namely,M$1,$M$2,$and M$3.$The standard cost and revenue per unit are as follows:

Selling pricek$400,$

Direct material A $5$kg at k$25$ pre kg $=125$

Direct material B $3$kg at k$22$ per kg$=66$

Direct labour $3$hours at k$10$ per hour $=30$

Valuable overheads $3$ hours at k$7$ per hour$=21$

Standard contribution$=158$

The budgeted production and sales for the period in question were $10,000$ units.Thise mix of materials be veried and there the usage variance can subdivided into mix and yield variance.For the oeriod under review $,$the actual results were as follows:

production and sales $9000$ units

Sales revenue $4,455,000$

Direct material A $35000$kg $910,000$
