Given that $a : b = 5 : 3$ and $b : c = 2 : 5$. Which of the following is true?
Answer & explanation
Correct answer: option 3
a : b = 5 : 3
b : c = 2 : 5
Here, we can see b is common in both ratio, so lets make b equal in both ratios:
a : b = 5 : 3 ) × 2 = 10 : 6
b : c = 2 : 5 ) × 3 = 6 : 15
We get,
a : b : c = 10 : 6 : 15
So, b < a < c
