Actual production 50000 standard price 15 actual price 5

Variance will be option >>>>>>>>>>>>>  A-500000 favorable

(Even though the figure seems to be exaggeration)

Material Price Variance = (Standard Price - Actual Price) * Actual Production

                                           = (15 -5 ) *50,000 Units

                                           =      10 *50,000

                                           =      500,000 Favorable

Favorable because we pay for material actually less than the standard. Therefore, this is favorable.

So, the option (A) is the Correct Ans. 

 A-.........>>>>>>>>>>>>>>>500000 favorable
