Question 63

If A : B = 4 : 5 and B : C = 20 : 11, then find A : B : C ?

Solution

Given = A : B = 4 : 5 and B : C = 20 : 11

=> $$\frac{A}{B}=\frac{4}{5}$$ -----------------(i)

and $$\frac{B}{C}=\frac{20}{11}$$ -----------------(ii)

Multiplying equation (i) by '4', we get : $$\frac{A}{B}=\frac{16}{20}$$

Now, the value of B is same in both equation, => A : B : C = 16 : 20 : 11

=> Ans - (C)
