Question

If A: B=2:3 and B:C = 4:5 then C:A is
A. 12:10
B. 8:5
C. 8:15
D. 15:8

Answer 1

Answer:

(D) 15:8

Step-by-step explanation:

(d) 15: 8 Because,

A: B = 2: 3 AND B: C = 4: 5

= (A/B) = (2/3) and (B/C) = (4/5)

= (A/B) × (B/C) = (2/3) × (4/5)

= (A/C) = (8/15)

= (C/A) = (15/8)

Hence, c : a = 15:8
