Answers
2 , 1 , 0.5 are in continued proportion
Step-by-step explanation:
Question is not Clear
Let say Box Has x
then Depending upon position of Box 3 possibilities are there
x , 1 , 0.5
1 , x , 0.5
1 , 0.5 , x
a , b , c are in continued proportion
if b² = ac
Case 1
x , 1 , 0.5
=> 1 ² = x (0.5)
=> x = 2
Case 2
1 , x , 0.5
=> x ² = 1 * 0.5
=> x = 0.707
Case 3
1 , 0.5 , x
=> 0.5² = 1 (x)
=> x = 0.25
from given option only x = 2 satisfies
Hence Case 1 Should be the Question :
2 , 1 , 0.5 are in continued proportion
