Question

a:b= 7:6, b:c= 6:5 and c:d = 4:3 then find a : b : c : d .
​

Answer 1

Answer:

a:b:c:d = 28 : 24 : 20 : 15

Step-by-step explanation:

given ratios are

a:b= 7:6, b:c= 6:5 and c:d = 4:3

Let's see formula

if A:B = x:y , B:C = p:q , C:D = m:n then

A:B:C:D = xpm : ypm : yqm : yqn

Using above formula we get

a:b:c:d = 7(6)(4) : 6(6)(4) : 6(5)(4) : 6(5)(3)

= Here 6 get cancelled in all ratio

= 7(4) : 6(4) : 5(4) : 5(3)

= 28 : 24 : 20 : 15

Therefore, a:b:c:d = 28 : 24 : 20 : 15
