Answer:
Step-by-step explanation:
1). Geometric mean of a and b = 
Therefore, geometric mean of 2 and 50 = 
= 10
2). By geometric mean theorem,


e² = 6 × 24
e = √144
e = 12
Similarly, 

d² = 6 × 30
d = √180
d = 6√5
And 

c² = 30 × 24
c = √720
c = 12√5
Answer:A
Step-by-step explanation: on edgunity
It would then cost $90 because 25% of $120 is $30
