Question 68

If $$A : B : C = 4 : 5 : 6$$, then what is the ratio of $$\left(\frac{1}{A}\right) : \left(\frac{1}{B}\right) : \left(\frac{1}{C}\right)$$?

Solution

Given = $$A : B : C = 4 : 5 : 6$$

Let $$A=4$$, $$B=5$$ and $$C=6$$

To find = $$\left(\frac{1}{A}\right) : \left(\frac{1}{B}\right) : \left(\frac{1}{C}\right)$$

= $$\frac{1}{4}:\frac{1}{5}:\frac{1}{6}$$

Multiply all the terms by L.C.M.(4,5,6) = 60

= $$15:12:10$$

=> Ans - (C)
