Given that a : b = 5 : 3 and b : c = 2 : 5

Which of the following is true?

a < b < c

b < c < a

b < a < c

a < c < b

✅ Correct Option: 3

Making b common: $a:b = 5:3 = 10:6$ and $b:c = 2:5 = 6:15$ . So $a:b:c = 10:6:15$ , giving $b < a < c$ .

Note: The NTA key marks option 4 ( $a<c<b$ ), but the correct combination of the given ratios yields $a:b:c = 10:6:15$ , i.e., $b<a<c$ .
