Solution

The correct option is A
8:6:10:9

A:B = $\frac{1}{2}$ : $\frac{3}{8}$ = 4:3

B:C = $\frac{1}{3}$ : $\frac{5}{9}$ = 3:5

C:D = $\frac{5}{6}$ : $\frac{3}{4}$ = 10:9

$\to$ A:B = 4:3, B:C = 3:5 and C:D = 5: $\frac{9}{2}$

$\to$ A:B:C:D = 4:3:5: $\frac{9}{2}$ = 8:6:10:9

If A:B = 12:38, B:C = 13:59 and C:D = 56:34, then the ratio A:B:C:D is

The correct option is A 8:6:10:9 A:B = 12:38 = 4:3 B:C = 13:59 = 3:5 C:D = 56:34 = 10:9 → A:B = 4:3, B:C = 3:5 and C:D = 5:92 → A:B:C:D = 4:3:5:92 = 8:6:10:9

If A:B = $\frac{1}{2} : \frac{3}{8}$ , B:C = $\frac{1}{3} : \frac{5}{9}$ and C:D = $\frac{5}{6} : \frac{3}{4}$ , then the ratio A:B:C:D is

The correct option is A
