If A : B = 2 : 3 and B : C = 4 : 5 then A : B : C is
A. 2 : 3 : 5
B. 5 : 4 : 6
C. 8 : 12 : 15
D. 6 : 4 : 5
Answer: Option C
Solution(By Examveda Team)
$$\eqalign{ & \frac{{\text{A}}}{{\text{B}}} = \frac{2}{3} \cr & \frac{{\text{B}}}{{\text{C}}} = \frac{4}{5} \cr} $$ A : B : C = 2 × 4 : 3 × 4 : 3 × 5 = 8 : 12 : 15This Question Belongs to Arithmetic Ability >> Ratio

If a : b : c = 3 : 4 : 7, then the ratio (a + b + c) : c is equal to
A. 2 : 1
B. 14 : 3
C. 7 : 2
D. 1 : 2
If $$\frac{2}{3}$$ of A=75% of B = 0.6 of C, then A : B : C is
A. 2 : 3 : 3
B. 3 : 4 : 5
C. 4 : 5 : 6
D. 9 : 8 : 10
A/B = 2/3 = 2*4/3*4 = 8/12
B/C = 4/5 = 4*3/5*3 = 12/15
Therefore, A:B:C = 8:12:15
