The value of 4b/a is 240.
Step-by-step explanation:
Given,
a x 60 = b
or
b = a x 60
Similarly, the value of a would be:
We need to find
Therefore, we have to put the either values of a and b in the specified equation:
Hence,
We have only put the value of one variable to evaluate or to make it variable free
or
Therefore, the value of 4b/a is 240.
(123.7*10^9)/(4*10^6)=$30,925
