Question

if four quantities a,b,c,d,be such that a:b=3:4,b:c=5:6,c:d=4:9 then find continued ratio of a,b,c,d.

Answer 1

Here, a = 3b/4, c = 6b/5, d = 9c/4 = 9*6b/4*5 = 27b/10 I write three numbers in form of other, any number you can take. Then,
a:b:c:d = 3b/4: b : 6b/5 : 27b/10 = 15 : 20 : 24 : 54
