Favourable variance is that variance which is good for business while unfavourable variance is bad for business
There are 7 variances associated with a budget ( which are generally calculated for controlling purposes) 1- Material Price variance 2- Material Quantity variance 3- Labor rate variance 4- Labor efficiency variance 5- Spending variance 6- Efficiency variance 7- Capacity variance
Equal in Variance
Pooled variance is a method for estimating variance given several different samples taken in different circumstances where the mean may vary between samples but the true variance (equivalently, precision) is assumed to remain the same. A combined variance is a method for estimating variance from several samples, given the size, mean and standard deviation of each. Mathematically, a combined variance is equal to the calculated variance of the set of the data from all samples. See links.
The variance is: 1.6709957376e+13
A favorable/unfavorable price variance does not effect your quantity variance. The reason you would see a favorable price variance and an unfavorable quantity variance is because you consumed more materials than your standard allows AND the price you paid for those material was less than your standard price. If you paid more than your standard price, you would have experienced an unfavorable variance in both quantity and price.
Favourable variance is that variance which is good for business while unfavourable variance is bad for business
a
Since actual usage of the direct material was greater than the standard allowed, the excess usage is called an unfavorable variance
actual usage of materials exceeds the standard material allowed for output
Unfavorrable direct labor price variance indicates that business has incurred more direct labor cost for production of units of product then standard labor cost. For example if standard cost of direct labor for producing 1 unit is 10 and company incurred 105 for making 10 units then extra 5 is unfavorable direct labor cost variance.

TRUE
Price variance is the actual unit cost minus the standard unit cost, multiplied by the actual quantity purchased. The variance is said to be unfavorable if the actual price of the materials is higher than the standard price of the materials.
If poor quality materials are used it may cause insufficient demand for the products. Insufficient demand may not keep workers busy. If the workers are not being laid off, and unfavorable labor efficiency variance will often be recorded.
1.rise in price. if price will be higher than the budgeted price then unfavourable 2.shortage of suppliers. this led to increase in price
