B. 169

C. 253.5

D. 338

E. None of these

Answer: Option D

Solution(By Examveda Team)

Let 40% of 265 + 35% of 180 = 50% of x
Then, $$\left( {\frac{40}{{100}} \times 265} \right)$$   + $$\left( {\frac{35}{{100}} \times 180} \right)$$   = $$\left( {\frac{50}{{100}} \times x} \right)$$
⇒ 106 + 63 = $$\frac{x}{2}$$
⇒ x = 169 × 2
⇒ x = 338
