Correct Answer - Option 3 : 6 : 8 :: 15 : 24
Formula Used:
Product of mean = Product of extreme
Calculation:
Option 1:
The product of mean = 20 × 15 = 300
The product of extreme = 25 × 12 = 300
This is satisfied the condition.
Option 2:
The product of mean = 10 × 36 = 360
The product of extreme = 45 × 8 = 360
This is satisfied the condition.
Option 3:
The product of mean = 15 × 8 = 120
The product of extreme = 24 × 6 = 144
This is not satisfied the condition.
∴ 6 : 8 :: 15 : 24 is not correct proportion.
