A. 74

B. 86

C. 92

D. 108

Answer: Option D

Solution(By Examveda Team)

Let the three parts be A, B and C
$$\eqalign{ & {\text{Let }}\frac{A}{2} = \frac{B}{3} = \frac{C}{4} = x \cr & {\text{Then, }}A = 2x,B = 3x{\text{ and }}C = 4x \cr & {\text{So, }}A:B:C = 2:3:4 \cr & \therefore {\text{Largest part :}} \cr & = \left( {243 \times \frac{4}{9}} \right) \cr & = 108 \cr} $$
