In an equation, A= B*C, the value of item A is known as:

Derived Value

The correct answer is option 3- derived value.

Here, the values B and C are Basic Values. While A is the Derived Value as it is obtained by multiplying B and C.

If quantity (Q) of an item is purchased at a price (P), the value of that item (V) is derived as follows:
V = Q × P.

Here, the values P and Q are Basic Values. While V is the Derived Value as it is obtained by multiplying Q with P. The expression (Q×P) is called as arithmetic expression. In general, an arithmetic expression may contain one or more functions.
