1) You know that a is 4/5 of b. This can be written as:
.
To find what b is equal to, multiply both sides by 5/4:
.
A is 5/4 B.
2) You know that a is 1/5 smaller than b. This can be written as:
.
To find b, just add 1/5 to both sides:
.
B is 1/5 bigger than a.

Answer:
Step-by-step explanation:
Given : The total number of programmers in the company = 30
The company wants to select a group of 6 programmers to work on a particular project.
Since the order of selecting them does not matters , therefore we use combinations.
The number of combinations of r things taken from n things is given by :-
here, n= 30 and r= 6
So the number of different ways to form they could select a group of 6 would be
i.e. Total ways =593775
In terms of factorials , the number of total ways to form they could select a group of 6 is .
