c. a = 0, b = 6 is the combination of a and b will yield the optimum for this problem
Given equation 4a+2b<=12
a=0,b=0
4*0+2*0<=12
0<=12
a=0,b=6
4*0+2*6=12
12<=12
only option a and c holds correct answer
now, check $6a+$15b
putting option c in above equation
6*0+15*6=90
hence option c is correct
a=0,b=6
The definition of yield is the theoretical yield multiplied by 100 and the actual yield. Numerous factors, which will be covered in later chapters of the course, can cause a chemical reaction's actual yield to be lower than its theoretical yield.Yield is a term used to describe the profits made and realised on an investment over a specific time frame. Based on the amount invested, the security's current market value, or its face value, it is expressed as a percentage. Yield is made up of the interest or dividends that come with holding a specific security.
