Question
If A: B = 1.2: 2, B: C = 1.5: 2, and C: D = 2: 3, then
B: D is equal to:Solution
A: B = 1.2: 2              …. (1) B: C = 1.5: 2             …. (2) By equaling B in both the cases we get 3rd case –  A: B: C =1.8:3:4 Now, 4th case C:D=2:3 Again, by equaling C in both case 3rd and 4th we get, A: B:C:D= 1.8:3:4:6 So, B: D = 3:6 or 1:2 B: D is equal to 1: 2
