If A : B = 4 : 5, B : C = 4 : 15 and C : D = 5 : 16 Than find the ratio between A and D :

15 : 1

1 : 15

15 : 16

4 : 5

✅ Correct Option: 2

Make B consistent: $A:B = 4:5 = 16:20$ and $B:C = 4:15 = 20:75$ , so $A:B:C = 16:20:75$ . Make C consistent with $C:D = 5:16 = 75:240$ . So $A:D = 16:240 = 1:15$ , which matches option 2.
