Constant of Proportionality = 15.20
What's proportionality?
Suppose there are two amounts. Proportionality indicates that if there's a change in the value of one number, the value of other number also changes but maintaining a constant ratio
Proportionality can be direct or inverse
Direct proportion
Two amounts are said to be in direct proportion if on increasing the value of one number, the value of other number also increases and vice versa.
For illustration cost of a commodity and volume of a commodity are in direct proportion
Inverse proportion
Two amounts are said to be in inverse proportion if on increases the value of one number, the value of other volume diminishes and vice versa.
For illustration Number of men and number of days taken by those men to complete a job
From the table, we can calculate the constant of proportionality
