Question 63

If $$u : v : w = 1 : 5 : 13$$, then what will be the value of $$\frac{(3u + 2v + 4w)}{(2w - u - 4v)}$$ ?

Solution

Given = $$u : v : w = 1 : 5 : 13$$

Let $$u=1$$, $$v=5$$ and $$w=13$$

To find : $$\frac{(3u + 2v + 4w)}{(2w - u - 4v)}$$

= $$\frac{3(1)+2(5)+4(13)}{2(13)-(1)-4(5)}$$

= $$\frac{3+10+52}{26-1-20}$$

= $$\frac{65}{5}=13$$

=> Ans - (B)
