VALET CO ( JUNE – 2014)

A) ii —- Calculates the total sales quantity contribution variance.?

sir how we will identify that question is asking is for yield variance not volume variance.
as volume and quantity are word expressed with same meaning.

in this question it is asking for yield variance.
(Actual quantity x Standard Proportion ) – ( budgeted Quantity ) * Standard contribution

but i mistakenly calculated like this – (Actual sales – Budgeted Sales ) x standard contribution

please help me so i never repeat same mistake again? how to differentiate between quantity variance and volume variance. hope i have explained my doubt clearly.
