A. $$\frac{3}{4}$$
B. $$\frac{4}{3}$$
C. 0
D. $$\frac{{55}}{4}$$
Answer: Option C
Solution(By Examveda Team)
$$\eqalign{ & x:y = 2:1 \cr & {\text{then, }}5{x^2} - 13xy + 6{y^2} \cr & \Rightarrow 5 \times 4 - 13 \times 2 \times 1 + 6 \times {1^2} \cr & \Rightarrow 20 - 26 + 6 \cr & \Rightarrow 0 \cr} $$This Question Belongs to Arithmetic Ability >> Algebra
